Harrison Earl Spangler (June 10, 1879 – 1965) was a politician from the U. S. state of Iowa.

Spangler was born in Guthrie County, Iowa, and served in the U.S. Army during the Spanish–American War. He studied to be a lawyer and joined the Republican Party.

Spangler was an Iowa delegate to the 1924, 1932, 1936, 1940, 1944, 1948 and 1952 Republican National Conventions. (In 1932 he was an alternate delegate.) He was chairman of the Iowa Republican State Central Committee 1930–32. He was also a member of the Republican National Committee 1931–49 and its chairman 1942–44.

While RNC chairman in 1943, Spangler created a council concerning foreign policy for the 1944 party's platform. He wanted a unified policy among isolationists and internationalists on treaty ratification and the proposed world peace organization.

Dewey of New York, Harry Kelly of Michigan, Dwight H. Green of Illinois, and Senator Robert A. Taft of Ohio.
