"Can't Smile Without You" is a song written by Christian Arnold, David Martin, and Geoff Morrow, and recorded by various artists including Barry Manilow and The Carpenters. The version recorded by Manilow in 1977 and released in 1978 is the most well-known version, though it was not the first to be recorded or released.

"Can't Smile Without You" was recorded by Manilow in 1977 and released on his 1978 album, Even Now. Manilow also issued the song as a single in 1978 where it reached No. 1 on the Billboard Adult Contemporary chart and No. 3 on the Billboard Hot 100 chart.

Manilow's version has slightly different lyrics from the Carpenters' version such as the Carpenters's line "I can't laugh and I can't walk/I'm finding it hard even to talk" which was changed in Manilow's version to "I can't laugh and I can't sing/I'm finding it hard to do anything". The Carpenters remixed the song with additional orchestration for the B-side of the 1977 "Calling Occupants of Interplanetary Craft" single, revising the lyrics to read "I can't laugh and I can't sleep/I don't even talk to people I meet".

A version on Manilow's greatest hits box set, The Complete Collection and Then Some..., contains a slightly different version to the previously released version.

The song was recorded in 1976 by The Carpenters and released on their May 1976 album, A Kind of Hush. It was also the B-side track for their 1977 single, "Calling Occupants of Interplanetary Craft", released in support of their 1977 album, Passage.

On behalf of the songwriters, publishing company Dick James Music sued George Michael for plagiarism in the mid-1980s claiming that the 1984 Wham! single, "Last Christmas", lifted its melody from "Can't Smile Without You". The case was settled out of court.
