Brian Albert Gordon Auger (born 18 July 1939) is an English jazz rock and rock music keyboardist who specialises in the Hammond organ. Auger has worked with Rod Stewart, Tony Williams, Jimi Hendrix, John McLaughlin, Sonny Boy Williamson, and Eric Burdon. He incorporated jazz, early British pop, R&B, soul music, and rock into his sound. He has been nominated for a Grammy Award.

In 1965, Auger played on “For Your Love” by The Yardbirds as a session musician. That same year, Auger formed the group The Steampacket with Long John Baldry, Julie Driscoll, Vic Briggs, and Rod Stewart. Due to contractual problems there were no official recordings made by the band; nevertheless, nine tracks were laid down for promotional use in late 1965 and released as an LP in 1970 in France on the BYG label. They were released on a CD by Repertoire Records in 1990 (licensed from Charly Records) as well as 12 live tracks from Live at the Birmingham Town Hall, February 2, 1964. Stewart left in early 1966 and soon thereafter the band broke up.
