The Statue of Liberty National Monument is a United States National Monument comprising Liberty Island and Ellis Island in the U.S. states of New Jersey and New York. It includes the 1886 Statue of Liberty by sculptor Frédéric Auguste Bartholdi and the Statue of Liberty Museum, both situated on Liberty Island, as well as the former immigration station at Ellis Island which includes the Ellis Island Immigrant Hospital.

In the United States, a national monument is a protected area that can be created from any land owned or controlled by the federal government by proclamation of the president of the United States or an act of Congress. National monuments protect a wide variety of natural and historic resources, including sites of geologic, marine, archaeological, and cultural importance. In contrast, national parks in the U.S. must be created by Congressional legislation. Some national monuments were first created by presidential action and later designated as national parks by congressional approval.
