List of passenger ships built in the United States

Shipyards in the United States built dozens of deepwater passenger ships from 1900 to 1958.

Their construction was spurred by the Merchant Marine Act of 1920, which says that only ships built and registered in the United States may sail solely between the country's ports^[1][2], and by the Merchant Marine Act of 1928, whose government loans led the International Mercantile Marine Company and other U.S. shipping lines to order new ships through World War II.^[2]

The largest passenger liner ever built in the United States was the SS United States, completed in 1952.^[3] The last large passenger liner to be completed was Moore-McCormack Lines' SS Argentina in 1958.^[4]

The only U.S.-built deepwater passenger ships still in existence are the United States (laid up), former converted cargo liner SS Medina (hotel ship), cargo/passenger liner NS Savannah (museum ship), and the partly US-built Pride of America (still in service).

Today, only small coastal and river passenger ships are still built in the U.S. and fly the American flag.
