Richard David De Wert (November 17, 1931 – April 5, 1951) was a United States Navy hospital corpsman who was killed in action during the Korean War while serving with a Marine Corps rifle company.

He was posthumously awarded the nation's highest military decoration for valor, the Medal of Honor, for heroic actions "above and beyond the call of duty" on April 5, 1951, in South Korea.

Landing with the 1st Marine Division at Inchon in September 1950, Hospitalman De Wert participated in operations to liberate the city of Seoul.

Still persistent in his refusal to submit to first aid, he resolutely answered the call of a fourth stricken comrade and, while rendering medical assistance, was himself mortally wounded by a burst of enemy fire.

His courageous initiative, great personal valor, and heroic spirit of self-sacrifice in the face of overwhelming odds reflect the highest credit upon HC Dewert and enhance the finest traditions of the U.S.
