Which Disneyland land was added in 1966? New Orleans Square was the first new land added after Disneyland opened.

New Orleans Square opened on July 24, 1966, and was designed around the architecture, food, music, and atmosphere of 19th-century New Orleans. The roughly three-acre area replaced Holidayland and cost about $18 million. Its opening ceremony included New Orleans mayor Victor H. Schiro, who helped dedicate the land with Walt Disney.

The land was planned during the late 1950s, with construction beginning in 1961 or 1962. Its arrival also changed the Disneyland Railroad: the Frontierland station was moved and later renamed New Orleans Square Station. Pirates of the Caribbean opened alongside the land in 1967, while the Haunted Mansion show building was also incorporated into the area.

A common mix-up is to confuse New Orleans Square with later additions such as Bear Country, Mickey's Toontown, or Star Wars: Galaxy's Edge. New Orleans Square remains distinctive because it is an original Disneyland land with no direct counterpart at Walt Disney World.
