John Henry Patterson (February 10, 1843 – October 5, 1920) was a Union officer during the American Civil War and a recipient of the Medal of Honor for courage under fire at the Battle of the Wilderness.

Patterson was born in Selkirk, New York and was commissioned as a First Lieutenant in the newly created 11th Infantry Regiment in May 1861.^[1] On May 5, 1864, under heavy fire from Confederate forces, Patterson left cover to rescue a wounded officer, who was in danger of both capture and death, as the forest near where he had fallen had caught fire during the battle. Patterson picked up the officer and carried him several hundred yards to safety.

Patterson remained in the Regular Army after the war. He rose through the officer ranks and became the commanding officer of the 20th Infantry Regiment on 28 September 1898. At the same time, he was promoted to Brigadier General in the U.S. Volunteers and held that position until he was promoted to Brigadier General in the Regular Army on 18 January 1899. He retired shortly afterwards on 6 February 1899. ^[2]

General Patterson was a companion of the New York Commandery of the Military Order of the Loyal Legion of the United States.
