The 15 cm schwere Feldhaubitze 1902 (English: "15 cm heavy field howitzer 1902") was a German heavy field howitzer introduced in 1903 and served in World War I.

It was the first artillery piece to use a modern recoil system in the German Army. Some 416 were in service at the beginning of the World War I.^[1] Its mobility, which allowed it to be deployed as medium artillery, and fairly heavy shell gave the German army a firepower advantage in the early battles in Belgium and France in 1914^[2] as the French and British armies lacked an equivalent. France had a Canon de 65 M with a recoil system, but used it only as a mountain howitzer.^[3]
