Agnes Mapes was an American actress who appeared in vaudeville performances and silent films throughout the 1900s and 1910s.

Originally a part of the Crescent Theatre Stock Company, she was highly praised for her role in the 1907 production of The Holy City.

Her multiple roles in 1912's A Fool There Was resulted from actors having to be swapped around which led to her playing the lead position and being applauded for her "fascinating and repellant" performance.

[2] Mapes was part of the Kalem crew that traveled to Ireland on July 3, 1911, to make films after the success of the Kalem film The Lad from Old Ireland,[3] acting as the wardrobe manager in addition to actress.

[4] After a series of tours throughout the highlands of Killarney, the Kalem crew produced seventeen films of varying lengths, including The Colleen Bawn and Arrah-na-Pogue.
