Merriam Modell (1908—July 1, 1994) was a Jewish-American author of pulp fiction who wrote under the pen-name Evelyn Piper.

A graduate of Cornell University, Modell travelled extensively in her younger years, and for a longer period of time, up to 1933, lived in Germany. Back in the United States, after marriage and motherhood (she had a son, John Modell), she published her first short story in 1941 and afterwards started to write novels as well.

She died of pulmonary embolism in Pittsburgh, Pennsylvania.
