Clara McDonald Williamson (November 20, 1875 – February 17, 1976) was a 20th century American painter who worked in the tradition of naïve art.

Like Grandma Moses, she started painting late in life and she achieved a national reputation despite the fact that her career lasted only two decades.

[3] Starting in 1943, Williamson took several classes in drawing and painting at Southern Methodist University and the Dallas Museum School.

[1] She quickly began working on what she called "memory paintings" that referred to incidents from her early rural life; these became a dominant theme in her oeuvre.

Examples include Chicken for Dinner (1945), The Girls Went Fishing (1945–46), Standing in the Need of Prayer (1947, showing a revival meeting by torchlight), Texas Barn Dance (1951), The Day the Bosque Froze Over (1953), and The Night Before Christmas (1954).

[1] Her palette was restrained, leaning towards desaturated greens, browns, and grays in middle and light tones that lent a luminous subtlety to the finished works.
