Two Sides of Leonard Nimoy is Leonard Nimoy's second album released shortly after Music from Outer Space.

It was released in early 1968 by Dot Records and reached 97 on the US album chart.

Side one showcases the side fans know as Mr. Spock but in a softer light, along with his struggle between being human and Vulcan.

Side two represents Nimoy's interests in a variety of songs: novelty, pop, country and love songs.

Side one of this album is presented on the Varèse Sarabande Records 1995 reissue of Leonard Nimoy Presents Mr. Spock's Music from Outer Space.
