"Alpha Beta Gaga" is a song by French electronic music duo Air from their third studio album, Talkie Walkie (2004).

It features acoustic guitar, synthesisers, shamisen, a string section, and a prominent whistling melody.

It was rumoured to have been one of the songs Air offered to Madonna to record for her 2003 album American Life after she asked them tentatively to work with her on it.

It is used as the introduction to episode one of season two of American TV series Castle.

The theme was also the signature tune of the Spanish cultural program "Miradas 2", which was broadcast by the public channel "La 2" (Radiotelevisión Española -RTVE-) until 2013.
