Edmund Burke Riley Jr. (April 2, 1914 – June 13, 2006) was an American Democratic legislator, lawyer and public official on territorial, state and national levels.

He graduated from Yakima Valley Community College and attended the University of Washington, but he ran out of money in 1937 and moved to Fairbanks, Alaska the following year.

During World War II, he served in the United States Army Air Forces as a courier in the Pacific Theater of Operations.

His term was cut short with the change of command from Harry S. Truman to Dwight D. Eisenhower, and he was succeeded as Secretary by Republican Waino Hendrickson.

Riley later worked in the United States Bureau of Land Management and the Department of the Interior.
