William Parish Chilton (August 10, 1810 – January 20, 1871) was an American politician and author who served as a Deputy from Alabama to the Provisional Congress of the Confederate States from 1861 to 1862.

He was a younger brother of Thomas Chilton, Representative from Kentucky and ghost writer of an "autobiography" by David Crockett.

Chilton originally opposed secession, but once Alabama decided to join the Confederate States of America he became a supporter.

On February 18, Davis arrived in Montgomery to take his oath of office; he was escorted into the capitol building by Chilton and Robert Rhett.

When the Confederate Congress was not in session Chilton served as a private in Harrison's Company of Alabama Rebels, a home guard unit.

After the war Chilton returned to practicing and teaching law, and writing; by 1870 he had managed to recoup most of his financial losses.
