Owen Wesley Siler (January 10, 1922 – July 17, 2007) was a United States Coast Guard admiral who served as the 15th commandant from 1974 to 1978.

Upon returning to the United States in April 1946, he briefly served as a personnel officer at the U.S. Coast Guard Training Center in Alameda, California, before his assignment as navigator of USCGC Taney.

His career with the U.S. Coast Guard included serving as a deck officer afloat, as an aviator performing search and rescue patrols, and ashore in the law enforcement, marine safety and environmental protection fields.

He also oversaw the expansion of the U.S. Coast Guard's marine environmental protection program, with the passage of the Fisheries Conservation and Management Act of 1976, which included an increase of the service's jurisdiction along the U.S. coastline to more than two million square miles.

Following his retirement from the U.S. Coast Guard, Siler moved to Savannah, Georgia, where he died from complications of heart failure on July 17, 2007, at the age of 85, and is buried in Arlington National Cemetery.
