Patrick Dougherty (born about 1844, date of death unknown) was a Union Navy sailor in the American Civil War and a recipient of the U.S. military's highest decoration, the Medal of Honor, for his actions at the Battle of Mobile Bay.
Born in about 1844 in Ireland, Dougherty immigrated to the United States and was living in New York when he joined the U.S. Navy.
At the Battle of Mobile Bay on August 5, 1864, Lackawanna engaged the CSS Tennessee at close range and the powder boy at the gun Dougherty was manning became a casualty.
Dougherty voluntarily took over the powder boy's duties, supplying gunpowder to his artillery piece throughout the battle.
Dougherty also aided in the attacks on Fort Morgan and in the capture of the prize ram Tennessee.
