The Piti Guns or Piti Coastal Defense Guns is the site of three Vickers-type Model 3 140-millimetre (5.5 in) coastal defense guns in the War in the Pacific National Historical Park in Piti, Guam. The Japanese manufactured these Model 3 coastal defense guns in 1914. During the Japanese Occupation of Guam from 1941-1944, they built up defensive positions on the island. The Chamorro population was forced to work in building up these defenses, and did so here at the Piti Guns.

The Piti guns were strategically placed in a village consisting mostly of rice paddies in 1944. This area was chosen to defend the beach at Asan from a possible invasion. These guns have a firing range of close to 10 miles (16 km) and were intended for use against ships and landing craft. When the United States Armed Forces came to retake the island on July 21, 1944 these guns were not fully operational. Consequently, not one of the three coastal defense guns was ever fired. However, these guns are representative of the type of weapons used by the Japanese on Guam for fortification efforts.[2]

One gun was toppled by a falling tree after the war.
