"'''K.K. Birthday'''" is a [[K.K. Slider]] song that first appeared in {{DnMe+}} as a live-only song and later reappeared as an obtainable one in {{NL}}. It is considered a [[secret song]], as it can only be obtained during a K.K. Slider performance on the [[player]]'s [[birthday]] (or the Saturday before in {{NL|short|nolink}}). None of the [[villager]]s own this song, although it will play in a villager's [[Villager house|house]] on the day of their birthday; if the villager already had a [[stereo]] with a song playing, it will be replaced by this song. In {{NH}}, it is one of five songs that cannot be reordered via [[Nook Shopping]] once obtained; the other four are "[[Animal City]]," "[[Drivin']]," "[[Farewell]]," and "[[Welcome Horizons]]."

In {{DnMe+}}, "K.K. Birthday" is not actually given a name, but is simply referred to by K.K. as '''バースデー・ライブ''' (''bāsudē raibu'', lit. "Birthday Live" meaning a "birthday live performance"). It can only be heard if there is another player in the village who leaves a message. K.K. will ask any other players to leave a birthday message on the Saturday before a player's birthday, when he normally appears. He will then appear on their actual birthday at any hour, for that player only, to perform the song alongside the birthday messages instead of the staff roll.  

Although "K.K. Birthday" is not present as one of K.K. Slider's songs in {{WW}} and {{CF}}, a unique instrumental arrangement of the song plays as background music when the player is first greeted by another villager upon starting the game on their birthday.

In {{NL}}, "K.K. Birthday" can be played in villagers' houses during their birthday. It also plays in the house of the villager that invites the player during their birthday. K.K. will perform this song on the Saturday near the player's birthday. Unlike {{DnMe+|nolink}}, K.K. gives an aircheck of this song. If the player's birthday is not on a Saturday, [[DJ KK]] will also play a DJ remix on that day in [[Club LOL]]. This is referenced in DJ KK's trophy description in {{SSB4|3ds}}.

In {{NH}}, "K.K. Birthday" can be played in a villager's house during their birthday. It also plays in the house of the villager that invites the player during their birthday. K.K. will also visit the island solely to perform this song on the player's birthday regardless of the day of the week, after which he will give the player the aircheck.  

In {{HHD}}, "K.K. Birthday" is played in the houses of [[Bunnie]], [[Jingle]], Melba, and [[Zipper T. Bunny|Zipper]].
