Executive Order 13792, entitled "Review of Designations Under the Antiquities Act," is an executive order issued by US President Donald Trump on April 26, 2017, that directed the Secretary of the Interior to review designations of national monuments made since 1996. The order applies to all new monuments greater than 100,000 acres in size and monuments that were expanded by at least 100,000 acres. Twenty-two land monuments and five marine monuments that were created by the administrations of Bill Clinton, George W. Bush, and Barack Obama were subject to review.
