Ambrosia is an American rock band formed in Los Angeles in 1970. Ambrosia had five Top 40 hit singles released between 1975 and 1980, including the Top 5 hits "How Much I Feel" and "Biggest Part of Me", and Top 20 hits "You're the Only Woman (You & I)" and "Holdin' on to Yesterday". Most of the original band members have been active with the group continuously since their 1989 reformation to the present day, with the notable exceptions of original guitarist and lead vocalist David Pack (who left in 2000) and original keyboardist Christopher North (who died in 2026).

Ambrosia currently tours internationally and has worked in the past and present with Alan Parsons, Bruce Hornsby, Bill Champlin, Michael McDonald, and Peter Beckett, among other notable artists.

The group was founded as a quartet with guitarist/vocalist David Pack, bassist/vocalist Joe Puerta, keyboardist Christopher North and drummer Burleigh Drummond. According to Joe Puerta, their original name was "Ambergris Mite," but after doing some touring they discovered there was already a band using the name "Ambergris," so they turned to the dictionary and picked the name "Ambrosia" because a name meaning "nectar of the gods" seemed fitting. While Ambrosia had several radio hits in the 1970s, much of the material on their five albums is progressive in nature.
