The USS Arizona Memorial, located at Pearl Harbor in Honolulu, Hawaii, marks the resting place of 1,102 of the 1,177 sailors and Marines killed on USS Arizona (BB-39) during the Japanese surprise attack on Pearl Harbor on 7 December 1941 and commemorates the events of that day. The attack on Pearl Harbor and the island of Oʻahu was the action that led to the United States' direct involvement in World War II.
The memorial, built in 1962, is visited by more than two million people annually. Accessible only by boat, it straddles the sunken hull of the battleship without touching it. Historical information about the attack, shuttle boats to and from the memorial, and general visitor services are available at the associated USS Arizona Memorial Visitor Center, which opened in 1980 and is operated by the National Park Service. The sunken remains of the battleship were declared a National Historic Landmark on 5 May 1989.
The USS Arizona Memorial is one of several sites in Hawaii and elsewhere that are part of the World War II Valor in the Pacific National Monument
