Dorothy Collins (born Marjorie Chandler;[1] November 18, 1926 – July 21, 1994) was a Canadian-American singer, actress, and recording artist.

In the late 1940s, she contributed vocals to the revived Raymond Scott Quintette, a sextet that released records on the bandleader's own Master label and served as house band on the radio program Herb Shriner Time.

Collins sang a collection of educational tunes on an album titled Experiment Songs, one of six LPs in a set called Ballads for the Age of Science, composed and produced by Hy Zaret and Lou Singer around 1960.

A number of these performances were issued in 2019 on the double album The Jingle Workshop: Midcentury Musical Miniatures 1951–1965, on the Modern Harmonic label.
