John Cridland Latham (March 3, 1888 – November 5, 1975) was a United States Army soldier who received the U.S. military's highest decoration, the Medal of Honor, for his actions in World War I.

Born on March 3, 1888, in Windermere, England, Latham immigrated to the United States and joined the Army from Rutherford, New Jersey.

On that day, near Le Catelet in northeastern France, he and two other soldiers, Sergeant Alan L. Eggers and Corporal Thomas E. O'Shea, left cover to rescue the crew of a disabled American tank.

O'Shea was killed in the process, but Latham and Eggers successfully defended the wounded tank crewmen from German fire all day and carried them to the safety of the Allied lines after nightfall.

Sergeants Latham and Eggers then returned to the tank in the face of the violent fire, dismounted a Hotchkiss gun, and took it back to where the wounded men were keeping off the enemy all day by effective use of the gun and later bringing it with the wounded men back to our lines under cover of darkness.
