Lillian Harmer (September 8, 1883 – May 14, 1946) was a prolific American character actress who, despite a brief career, became a familiar face in 1930s cinema. She appeared in over 60 films during the decade, often in small, uncredited parts that added memorable texture to the screen. While many of her roles were brief, Harmer earned featured supporting parts and notably portrayed the famous temperance activist Carrie Nation in the historical drama The Bowery (1933). Her filmography also includes appearances in major productions such as the 1931 adaptation of Huckleberry Finn, the star-studded Alice in Wonderland (1933), and the original 1937 version of A Star is Born.
