Tommy Mars (born Thomas Mariano on October 26, 1951)[1] is an American keyboard player known for his work with Frank Zappa.

In a 1980 interview in Keyboard magazine, Mars described one of the more unusual jobs he had as follows - "I was working in this revolving organ bar in Kodiak, Alaska, with Japanese and Russian fishermen kicking me in the back if I couldn't play an ethnic folk song to their drunken satisfaction".

In 2007 Strange News From Mars was presented, a jazz hybrid with Jon Larsen, on Zonic Entertainment, featuring Bruce Fowler, Jimmy Carl Black, Arthur Barrow, and other Zappa alumni.

In 2010 Tommy Mars recorded the surrealistic audio book Willie Nickerson's Egg, written by Jon Larsen, released in 2011.

At the Molde Jazz Festival 2014 Tommy Mars performed Willie Nickerson's Egg live (three sold-out concerts), together with Arthur Barrow, Arild Andersen, Jon Larsen, etc.
