Koo Koo Roo was an American fast casual restaurant chain specializing in charbroiled chicken founded in 1988 by Los Angeles-based restaurateurs Mike and Ray Badalian. The name "Koo Koo Roo" was an onomatopoeic reference to the crow of a rooster. After a series of expansions and ownership changes, in which Koo Koo Roo struggled for profitability throughout the 1990s, the last location in Santa Monica, California, closed in 2014.
