USCGC Duane (WPG-33/WAGC-6/WHEC-33) (earlier known as the USCGC William J. Duane) was a cutter in the United States Coast Guard. Her keel was laid on May 1, 1935, at the Philadelphia Navy Yard, Philadelphia, Pennsylvania. She was launched on June 3, 1936, as a search and rescue and law enforcement vessel.

The Treasury-class Coast Guard cutters (sometimes referred to as the "Secretary" or 327-foot class) were all named for former Secretaries of the Treasury Department. The cutter Duane was named for William J. Duane, who served as the third Secretary of the Treasury to serve under President Andrew Jackson.

At the time of the Duane's decommissioning in 1985, she was the oldest active U.S. military vessel; the current oldest, the USCGC Eagle, was also built in 1936 for the German military, but only commissioned into U.S. service in 1946 after being ceded as a war reparation after World War II.
