Colonel Les Claypool's Fearless Flying Frog Brigade (also known as The Les Claypool Frog Brigade) is a musical project with rotating personnel, led by American singer/bassist Les Claypool. The Frog Brigade was formed during a hiatus from Claypool's main group Primus.

The original band was formed in summer 2000 and consisted of Claypool, Todd Huth (guitars, vocals), Jay Lane (drums), Jeff Chimenti (keyboards), Skerik (saxophone), and Eenor Wildeboar (guitars, cümbüş). Les Claypool has described their sound as, "It's kind of a King Crimson meets Pink Floyd meets Frank Zappa type thing."

The band released two live recordings in 2001, Live Frogs Set 1 and Live Frogs Set 2. Set 1 is a mix of covers and originals, including "Thela Hun Ginjeet" (King Crimson) and "Shine On You Crazy Diamond" (Pink Floyd). Set 2 is a live cover of the entire Pink Floyd album, Animals. A studio album, entitled Purple Onion, was also released in 2002.

All three albums were released on Les Claypool's Prawn Song Records.
