The Breakers is a Vanderbilt mansion located on Ochre Point Avenue, Newport, Rhode Island, United States on the Atlantic Ocean. It is a National Historic Landmark, a contributing property to the Bellevue Avenue Historic District, and is owned and operated by the Preservation Society of Newport County.

Designed by renowned architect Richard Morris Hunt and with interior decoration by Jules Allard and Sons and Ogden Codman, Jr., the 70-room mansion encompasses 138,300 square feet of space on 5 floors. The home was constructed between 1893 and 1895.

The footprint of the house covers approximately an acre of the 13-acre estate on the cliffs overlooking the Atlantic Ocean.
