Zachariah Cantey Deas (October 25, 1819 – March 6, 1882) was a Southern United States cotton broker and soldier.

After the war, he became a prominent cotton broker in Alabama and amassed a significant fortune from his speculation.

He was commissioned as colonel of the 22nd Alabama, a regiment he helped raise and equip, purchasing 800 Enfield rifles with gold.

He was appointed as a brigadier general on December 13, 1862, and fought at the Battle of Chickamauga, where his men routed the Union division of Philip H. Sheridan and killed Brig.
