Lynn Merrick, born Marilyn Llewelling (1919-March 25th, 2007) was an actress from Fort Worth, Texas, and a B-Western heroine of the 1940's. In 1940, Merrick was one of thirteen women selected by the Motion Picture Publicists Association as a "Baby Star", a selection process which was meant to highlight the most promising new film stars.

Merrick made the bulk of her films during 1940, starring in 22 feature films for Republic Pictures. Sixteen of those films were Don Barry westerns. Her first Barry film was Two Gun Sheriff, and her last was Fugutive from Senora. She later worked for Columbia Pictures, where she starred in films alongside Richard Dix, Chester Morris, and Warner Baxter.

By 1947 she, for all practical purposes, had retired from acting. Her final film was actually in 1954, titled Escape from Terror starring and directed by Jackie Coogan. She had no known roles between 1947 and 1954, and none following 1954. During her career spanning 1940 to 1947, she starred in 45 films. She was married and divorced twice. Her first marriage was to actor Conrad Nagal, and her second was to producer Robert Goelet Jr. She had no children. She died on March 25th, 2007, at her home in West Palm Beach, Florida.
