"Atomic Dog" is a song by George Clinton from his 1982 album Computer Games. The track was released as a single in December 1982 and became the P-Funk collective's last to reach #1 on the U.S. R&B Chart. The single failed to reach the Top 100 of the Pop Chart although it has attained stature since partly to its having been sampled in several hip hop songs.

George Clinton’s P-Funk reached its commercial and conceptual height during the late 1970s after the release of Mothership Connection and a series of spectacular concert tours. Each of these concerts ended with a climactic descent of a giant spaceship from the rafters. However, as the band and their concept of funk grew, the organization became entangled in internal dissension, legal disputes, and creative exhaustion. “Atomic Dog” was the P-Funk collective’s last single to reach #1 on the U.S. R&B chart.

According to Clinton, most of the song's lyrics were ad-libbed during the recording process.

Although "Atomic Dog" is now regarded a classic in black popular music, it was at first held back from radio stations. George Clinton’s bad reputation in the industry, his political consciousness (as seen in his previous albums and recordings), and a general move towards more youthful-looking acts, kept his songs from being circulated on radio stations. Only after very strong sales was the song finally put on the air. The single “Atomic Dog” was released in December 1982 and reached #1 on the R&B charts, but missed the Hot 100 by just one position.

The song has been included in trailers and TV spots for many films (many dog-related), including 102 Dalmatians, Toy Story 2, Rugrats Go Wild, Hotel for Dogs, The Shaggy Dog, Finn on the Fly, Legally Blonde 2, Fresh Prince of Bel-Air, Boomerang and Menace II Society.
