The USS Arizona Memorial, located at Pearl Harbor in Honolulu, Hawaiʻi, marks the resting place of 1,102 of the 1,177 sailors killed on the USS Arizona during the attack on Pearl Harbor on December 7, 1941 by Japanese imperial forces and commemorates the events of that day. The attack on Pearl Harbor and the island of Oʻahu was the action that led to United States involvement in World War II.

The memorial, dedicated in 1962, is visited by more than one 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, opened in 1980 and operated by the National Park Service. The sunken remains of the battleship were declared a National Historic Landmark on 5 May 1989.
