Physicist is the third solo album by Canadian metal musician Devin Townsend, released on June 26, 2000 by his own Hevy Devy label and by InsideOut Music (see 2000 in music).

It is distinguished from the rest of Townsend's solo portfolio for the crossing of the style of his work in Strapping Young Lad with elements that had been explored in Ocean Machine: Biomech and Infinity.
