Mary Noble, Backstage Wife is an American soap opera radio program that details the travails of Mary Noble, a girl from a small town in Iowa who came to New York seeking her future.

Vivian Fridell had the title role from 1935 until the early 1940s. It was then taken over by Claire Niesen, who continued as Mary Noble until the end of the series. Mary's husband, Larry Noble, was portrayed by Ken Griffin, then James Meighan and finally, Guy Sorel. The music was supplied by organist Chet Kingsbury.

Each episode opened with the announcer (Pierre Andre, Roger Krupp, others) explaining:
Now, we present once again, Backstage Wife, the story of Mary Noble, a little Iowa girl who married one of America's most handsome actors, Larry Noble, matinée idol of a million other women — the story of what it means to be the wife of a famous star.
