Daniel D. Fernández (June 30, 1944 – February 18, 1966) was a United States Army soldier in the Vietnam War who received the U.S. military's highest decoration, the Medal of Honor, for his actions in Hậu Nghĩa province, Republic of Vietnam, in February 1966 — throwing himself on a live grenade, he sacrificed his life to save lives of the soldiers around him.

On February 18, 1966, in Củ Chi, Hậu Nghĩa province, his 16-man patrol was ambushed by a Viet Cong rifle company and forced to fall back.

[4] His official Medal of Honor citation reads: For conspicuous gallantry and intrepidity at the risk of his life above and beyond the call of duty.

Fernández, a sergeant and 2 other volunteers immediately fought their way through devastating fire and exploding grenades to reach the fallen soldier.

While first aid was being administered to the wounded man, a sudden increase in the accuracy and intensity of enemy fire forced the volunteer group to take cover.

Fernández' profound concern for his fellow soldiers, at the risk of his life above and beyond the call of duty are in the highest traditions of the U.S. Army and reflect great credit upon himself and the Armed Forces of his country.

[1] A Requiem Mass was held for Fernández at Los Lunas High School prior to his burial at Santa Fe National Cemetery.
