List of voice actors

Voice actors (, Voice actor) are people who record their voice for use in media, particularly to represent fictional characters. The following is a list of all known voice actors to contribute to the  series, sorted by last name:

Other or Unknown Role

Archived recordings
While many characters have voice clips specifically recorded for the Super Smash Bros. games, just as many reuse existing ones from previous entries or their home series. Notable examples include:
 * Yoshi, Jigglypuff, and Captain Falcon are the only fighters to have voice clips reused in all games beyond Smash 64—Yoshi is unique among them in that he also reused voice clips in Smash 64.
 * Jigglypuff is unique in that it has received new voice clips in other languages (Japanese in Melee and Ultimate, French in Melee and Brawl, German in Brawl); only its English clips have been reused.
 * While Captain Falcon has used the same voice clips in each game (albeit with variations between Smash 64, Melee, and Brawl onwards), he was given new vocals in Min Min's reveal trailer; Ryō Horikawa reprised his role for this appearance.
 * Inversely, Kirby receives new voice clips in all five games while still being voiced by the same actress, Makiko Ōmoto. This also applies to Ness (who is also voiced by Ōmoto), with the exception of him having no new voice clips in Ultimate, unlike Kirby.
 * Though the cast of the Pokémon anime was replaced prior to Brawl's release, coinciding with its localization moving from 4Kids Entertainment to The Pokémon Company International, the Smash Bros. series continues to use reuse archive audio from the 4Kids dub for Pokémon such as Jigglypuff and Snorlax, rather than their current actors. Other Pokémon such as Eevee and Togedemaru use their Japanese voices in the Smash Bros. series despite having dubbed voices in the anime.

Casting notes

 * The English voice recordings for Super Smash Bros. 4 and Ultimate were conducted under non-union conditions, which is presumed to be the cause of noticeable impacts on the voice casts of characters from Final Fantasy, Kid Icarus: Uprising, and Fire Emblem Awakening:
 * The only Kid Icarus: Uprising voice actors to reprise their roles in Smash are Antony Del Rio (Pit and Dark Pit) and (Viridi), both of whom are uncredited. Additionally, Walch only returned as Viridi for Smash 4, being completely replaced by Dayci Brookshire for Ultimate. All other Uprising characters were recast.
 * Cloud and Sephiroth are only voiced in Japanese.
 * From Smash 4 onward, Lauren Landa took over as the voice of female Robin instead of Michelle Ruff or Wendee Lee, who portrayed the three voice options for her in Awakening (although both of those actresses have since portrayed other Fire Emblem characters). Additionally, Laura Bailey's performance as Lucina is uncredited, as it has been in every Fire Emblem game except Fates.
 * As of 2017, Bailey has left the role of Lucina, as part of a noticeable exodus of unionized voice talent from the series, and has been replaced by Alexis Tipton. Due to its reuse of Smash 4 voice assets, Ultimate is the only time since 2017 that Bailey has portrayed Lucina in any capacity.
 * In addition to the above, several members of the cast in Brawl had replaced voice actors, for unknown reasons—though Fox, Slippy, and Krystal kept their voices from Assault (the most recent Star Fox game with voice acting at the time of Brawl's release), Falco, Wolf, Peppy, Leon, and Panther all gained new voices, with Mike Madeoy (Falco), Grant Goodeve (Wolf), Henry Dardenne (Peppy), and David Scully (Leon and Panther) replaced with Dex Manley (Falco and Peppy), Jay Ward (Wolf), Jim Walker (Leon), and Eric Newsome (Panther).
 * Every Smash game has introduced at least one playable character with a voice actor who never portrayed them outside of Smash. Namely:
 * Smash 64 introduced Ness and Captain Falcon.
 * Melee introduced the Ice Climbers.
 * Brawl introduced Pokémon Trainer, Lucas and Zero Suit Samus. Meta Knight and Pit also share this distinction as well, albeit only applying in English.
 * Smash 4 introduced Little Mac. Palutena also shares this distinction, albeit only in English.
 * Ultimate introduced Eight.
 * Kirby, Pit (Japanese), Wolf (English), Roy (Japanese), female Robin (English), and Solo also initially shared this distinction as well, until the release of Kirby 64: The Crystal Shards, Kid Icarus: Uprising, Starlink: Battle for Atlas, Fire Emblem Heroes, and Dragon Quest Monsters: The Dark Prince, respectively.
 * Lucario, in English, falls under this distinction as well, though Pokémon the Series: Diamond and Pearl first aired two years before Brawl was released; Lucario's first appearance in the series was shortly after Brawl's release, where was voiced by Bill Rogers. Similarly, Erdrick falls under this distinction as well, though Dragon Quest Rivals Ace was released a year before Ultimate; a special card pack with him was added in an update to the game after Hero was released in Ultimate, with Erdrick voiced by Nobuyuki Hiyama.
 * As of Smash 4, Mewtwo also falls under this distinction as well. Ultimate also added female Pokémon Trainer, Sheik, Zelda (in English), and the Mii Fighters.
 * Ultimate is the first game with official voice acting for Erdrick, Solo, and Eight, and Masahiro Sakurai shared some interesting pieces of trivia about each of the Hero's voice actors and their recording sessions:
 * The Luminary's voice actress, Mitsuki Saiga, reprises her role from Dragon Quest XI S (thus technically making Ultimate her debut voicing the character), but was directed to have more energy in her vocals to better fit the style of Smash.
 * Erdrick's voice actor, Nobuyuki Hiyama, had also notably voiced Adult Link in Ocarina of Time, Smash 64, and Melee. Of the four Heroes, his recording session was completed the fastest due to his extensive experience. Sakurai also notes that his performance can be recognized as Guy Shishioh from . In Dragon Quest XI S, he also voices Erdwin, a past hero based on Erdrick.
 * Solo's voice actor, Takeshi Kusao, asked for a lot of detail on the backstory of the protagonist to help improve his performance.
 * Eight's voice actor, Yūki Kaji, apparently dreamed of doing voice work for the Dragon Quest and Super Smash Bros. series, and he was enthusiastic to fulfill both at the same time in Ultimate.

Crediting errors

 * Charles Martinet's surname is misspelled "Martinee" in the credits of the original Super Smash Bros., an error also seen in a few other N64 games. This spelling may be an Anglicized form of the name's pronunciation.
 * Several actors are credited in Super Smash Bros. Ultimate despite having no performances actually in the game:
 * Jaz Adams and Lyssa Browne, who were the English voices of Peppy Hare and Slippy Toad in the Orbital Gate Assault stage's Smash Taunt in Smash 4, are still credited despite the stage not returning for Ultimate.
 * is credited despite having never portrayed any character in a Smash game. As she is the current English voice actress for Lyn in games released from 2017 onward, it is possible that this is some sort of mix-up relating to the possibility of her reprising that role; Ultimate instead reuses Lani Minella's portrayal of the character from Brawl and Smash 4. This makes her, along with Lucina, one of the only Fire Emblem characters in Ultimate to not be portrayed in some capacity by their current English voice actors.
 * Both and  are credited in the game's full credits (which includes voice actors for DLC characters, something the credits for Classic Mode did not add); it is unknown exactly why they are credited, as, while they do reprise the role of  for 's reveal trailer, Solon has no in-game role.
 * In Ultimate, Travis Willingham (the English voice of Knuckles the Echidna and Guile) is mistakenly credited twice in the "Help" menu's credits, by both his real name and "Kent Hampton". In World of Light and Classic Mode, he is only credited as the latter. Kent Hampton is the pseudonym that Travis Willingham is credited under in the Sonic the Hedgehog series, among other titles.
 * Rosalina's voice actress's name is misspelled as "Kerry Kane" instead of "Kerri Kane" in Ultimate's credits.
 * Eric Newsome, Meta Knight's English voice actor, mistakenly labeled the Super Smash Bros. franchise as the Super Mario Bros. franchise on his website. The link for the series on the website is also erroneously a duplicate link to the website for , in which Newsome voices multiple characters.
 * In a similar vein, Reuben Langdon, Ken's English voice actor, mistakenly claimed to have portrayed Raiden from in a Super Smash Bros. game (likely via motion capture, as Raiden's voice is portrayed throughout the Metal Gear series by ). This led many fans to conclude that he had accidentally leaked the inclusion of Raiden in the then-upcoming fourth entry, before later correcting himself and stating that he had mixed Super Smash Bros. up with PlayStation All-Stars Battle Royale.

Trivia

 * Sean Barrett (the English voice of Azurda) is the oldest voice actor in the series to record new lines for a character, being 80 years old at the time of Pyra and Mythra's release.
 * Michele Knotz has voiced the most individual characters in the Smash series, at 11.
 * With Ultimate marking his 100th performance as Mario, Charles Martinet received a certificate for the most performances as a single video game character.
 * Pokémon Trainer has the most voice actors in the entire series, totaling at 18. Wii Fit Trainer previously held the title, and still holds the record for the most voice actors in a single game, having 17 in Smash 4 and Ultimate.
 * Wii Fit Trainer is the only character to have different voice actors for different regional dialects. This is seen in the distinction between American and British English as well as Latin American and European Spanish. Because of this, Wii Fit Trainer is also the only character to feature up to four voice actors in a single language.
