"Hella Good" is a song written by Gwen Stefani, Tony Kanal, and The Neptunes for No Doubt's fifth studio album Rock Steady (album) (2001). The song draws influence from electro, rock, and funk music. It received positive reviews from music critics, who made comparisons to the work of a diverse range of artists such as Afrika Bambaataa and Madonna.

"Hella Good" was released as the album's second single in April 2002 (see 2002 in music). It was moderately successful, and Roger Sanchez's remix of the song topped the Billboard Hot Dance Music/Club Play. At the 45th Grammy Awards, "Hella Good" was nominated for Best Dance Recording, and Sanchez's remix won for Best Remixed Recording, Non-Classical. A black-and-white music video was produced, featuring the band squatting in an abandoned ship.
