Ola Lee Mize (August 28, 1931 – March 12, 2014) was a United States Army officer and a recipient of the Medal of Honor for his actions in the Korean War.

After several years of working for low pay, he attempted to enlist in the Army, but was rejected for being too light, at 120 pounds (54 kg).

Mize organized defensive positions, rescued wounded soldiers, and engaged the enemy until reinforcements arrived about noon the next day.

Colonel Mize is credited for being the officer responsible for starting the present day Combat Divers Qualification Course in Key West, FL.

Mize, a member of Company K, distinguished himself by conspicuous gallantry and outstanding courage above and beyond the call of duty in action against the enemy.

Company K was committed to the defense of "Outpost Harry", a strategically valuable position, when the enemy launched a heavy attack.

On returning to the main position he established an effective defense system and inflicted heavy casualties against attacks from determined enemy assault forces which had penetrated into trenches within the outpost area.

Mize's valorous conduct and unflinching courage reflect lasting glory upon himself and uphold the noble traditions of the military service.

On May 14, 2015, the Special Forces Underwater Operations School in Key West, Florida, celebrated its 50th anniversary by naming its headquarters building in his honor.
