Marcie Blane (born Marcia Blank, May 21, 1944, Brooklyn, New York) is an American singer who recorded pop music. The Seville record label issued a demo performed by the high school student as a favor for a friend. The song was "Bobby's Girl", which was followed by "What Does a Girl Do".

Released in the fall of 1962, "Bobby's Girl" made #2 on the Cash Box chart and #3 on the Billboard Hot 100, and was later recorded for the German market in their language. It sold over one million copies by 1963, and was awarded a gold disc. In the United Kingdom the song was covered by Susan Maughan who had the hit. "What Does A Girl Do?", the follow-up single, rose to #82 on the Hot 100 list in early 1963, and was Blane's only other appearance on any Billboard chart. Around 1965 Marcie retired from the music business and, as of the early 1990s, was a music and arts educator in New York.
