Dudley Chase Haskell (March 23, 1842 – December 16, 1883) was an American merchant, Civil War veteran, and Republican Party politician from the Lawrence, Kansas, area.

In that capacity, he helped gain congressional authorization for construction of three off-reservation Indian boarding schools, and the location of one in Lawrence, Kansas.

He lived in Pikes Peak, Colorado, until 1861, when he returned to Missouri to enter Union ranks after war broke out.

During the Civil War, Haskell served as an assistant to the quartermaster of the Union Army in Missouri, Arkansas, Kansas, and the Indian Territory in 1861 and 1862.

In 1876 Haskell was elected a Republican from Kansas's 2nd congressional district to the United States House of Representatives, serving from 1877 until his death in Washington, D.C., on December 16, 1883.
