Beryl Mercer (13 August 1882 – 28 July 1939) was a Spanish-born American-based actress of the 1920s and 1930s.
Born to British parents in Seville, Mercer was best known for her motherly roles in film and regularly appeared as a grandmother or cook or maid in some high profile films. She appeared in more than fifty films between 1916 and 1939 but her career was at a peak in the 1930s when she regularly starred in between five and ten films a year.
