Happy, Happy Birthday Baby" is a 1957 song written by Margo Sylvia & Gilbert Lopez. "Happy, Happy Birthday Baby" was originally performed by The Tune Weavers, who had their only hit with this song. Both Margo Sylvia and Gilbert Lopez were members of The Tune Weavers.

The inspiration for the song came from Margo's then-boyfriend, Donald Clements, who was a member of a group called the Sophomores. When he broke up with her, Margo came up with the lyrics to express how she wanted to stay with him. "The words came so easily. It was real," she recounted to Wayne Jancik in The Billboard Book of One-Hit Wonders. Margo and the rest of the Tune Weavers recorded it and "Ol' Man River" in an 18-hour session on March 7, 1957, in Boston, with Margo eight months pregnant. Seven months later, the song reached its peak of popularity in the United States.
