Margaret Hayes (born Florette Regina Ottenheimer; December 5, 1913[1] – January 26, 1977) was an American film, stage, and television actress.

A native of Baltimore, Maryland, Hayes was one of four children born to Clara Bussey and Jacob Lewis "Jack" Ottenheimer, erstwhile songwriter, joke-book writer, radio performer turned real estate broker, who had, at one time, reportedly provided much of the material for the famous magician, Howard Thurston.

[4] Using the name "Dana Dale" (reportedly at the suggestion of columnist Walter Winchell[2]), Hayes found work as a model, "featured in the best cigarette, auto, and fashion advertisements".

She made four guest appearances on CBS's Perry Mason, including as defendant Sybil Granger in 1957 episode "The Case of the Nervous Accomplice".

After marrying Herbert Bayard Swope in 1946, Hayes temporarily retired from acting and turned to journalism, eventually becoming assistant fashion editor for Life.
