The Best of Mountain is the first compilation by American hard rock band Mountain. It consists of material recorded throughout 1970-1971, culled from their first three LPs. On April 15, 2003, the album was remastered and reissued in an expanded edition with new liner notes and four bonus tracks, two of which are taken from Leslie West's first solo album, 1969's Felix Pappalardi-produced Mountain, the project which eventually led to the formation of the band.
