Mint 400 is the debut studio album by the Australian alternative rock band Ammonia, released on 16 October 1995 in Australia by Murmur and on 19 March 1996 in the US by Epic Records.

The album takes its title from the off-road desert race described in Hunter S. Thompson's book Fear and Loathing in Las Vegas.

Recorded in ten days at Festival Studios in Sydney, the recording captured the band's live sound, avoiding excessive overdubs and studio manipulation.

Mint 400 was an immediate hit in Australia, debuting in the National Album charts at Number 15.

All tracks written by Allan Balmont and Simon Hensworth and Dave Johnstone.
