Gerry Mulligan Quartet Volume 1 is an album by saxophonist and bandleader Gerry Mulligan featuring performances recorded in 1952 and originally released as the first 10-inch LP on the Pacific Jazz label.

[1][2] In 2001 Pacific Jazz released an album on CD with additional tracks from Mulligan's first five recording sessions.

The Allmusic review by Ken Dryden noted "Their unique approach to music came to be labeled as "cool" or West Coast jazz, relying on intricate improvisations, with Mulligan's inventive, lyrical baritone being well complemented by Baker, an unschooled player who possessed a gift for playing by ear".
