Meaning and origin of Marilyn

Marilyn is an English name that means “blend of Mary and Lynn”.

Marilyn is a twentieth-century creation that combines Mary with the popular name ending -lyn. Through Mary it connects to the Hebrew Miryam, a name of debated meaning. Marilyn became widely used in the United States in the early and middle twentieth century, and it will always be associated with Marilyn Monroe, the film star who adopted it as her screen name. Other bearers include the opera singer Marilyn Horne. The name sounds warm and glamorous, with a strong vintage feel that some parents now find ready for revival. Mari and Lynn are possible nicknames.

Other spellings with the same sound: Marilynn.
