"Baby I'm Yours" is a song written by Van McCoy which was a hit in 1965 for Barbara Lewis.

Van McCoy wrote "Baby I'm Yours" while working as a staff writer for April-Blackwood Music, the publishing arm of Columbia Records. However the first evident recording of the song - subsequent to the demo cut by Van McCoy himself - was made by Atlantic artist Barbara Lewis in a January 8, 1965 Atlantic Recording Studios (NYC) session "directed by" Bert Berns with the producer credit assigned to Lewis's manager Ollie McLaughlin. The session for the track featured George "Teacho" Wiltshire conducting his orchestra whose personnel included Clark Terry and Dud Bascomb (trumpets), Jimmy Cleveland and Tony Studd (trombones), Frank Haywood Henry (baritone sax), Charlie Brown (tenor sax), Paul Griffith (piano), Bill Suyker (guitar), Jimmy Lewis (bass), and Gary Chester (drums): the chorale vocal on the track was provided by the song's composer Van McCoy singing with Kendra Spotswood.
