Ajax is an oil-on-canvas painting by the American artist John Steuart Curry, created in 1936–1937.

The painting is on view at the Smithsonian American Art Museum, in Washington, D.C.[1] The painting was made with the intention to reassure Americans after the Dust Bowl years.

[2] Curry featured Ajax the bull in several of his works, such as the mural Kansas Pastoral.

The subject also became a target for mockery among those who opposed regionalist painting and considered it superficial.

The satirist Marshall Glasier mocked both Ajax and Curry's position at the University of Wisconsin with his 1948 painting John Steuart Curry and the University of Wisconsin Bull-Breeding Machine.
