USS New Orleans (LPH-11) was an Iwo Jima-class amphibious assault ship in the United States Navy. She was the third Navy ship to be so named, and is the first named for the Battle of New Orleans, which was the last major battle of the War of 1812.

The Iwo Jima-class amphibious assault ships of the United States Navy were the first amphibious assault ships designed and built as dedicated helicopter carriers, capable of operating up to 20 helicopters to carry up to 1,800 marines ashore. They were named for battles featuring the United States Marine Corps, starting with the Battle of Iwo Jima. The first ship of the class was commissioned in 1961, and the last was decommissioned in 2002. The hull classification of "LPH" stands for "Landing Platform Helicopter".
