The White Horse Tavern was constructed before 1673 and is believed to be the oldest tavern building in the United States. It is located on the corner of Farewell and Marlborough streets in Newport, Rhode Island.

English immigrant Francis Brindley constructed the original building on the site in 1652 on land obtained from his brother-in-law William Coddington. In 1673, he sold the lot to William Mayes, who enlarged the building to become a tavern. It was also used for large meetings, including as a Rhode Island General Assembly meeting place, a courthouse, and a city hall. Mayes obtained a tavern license in 1687, and his son William Mayes Jr. operated it through the early eighteenth century. The operation was named "The White Horse Tavern" in 1730 by owner Jonathan Nichols.

Loyalists and British troops were quartered there during the British occupation of Newport in the American Revolution, around the time of the Battle of Rhode Island. Newport's Van Bueren family donated money to the private Preservation Society of Newport to restore the building in 1952, after years of neglect as a boarding house. After the restoration, it was sold and once again operated as a private tavern and restaurant, and it remains a popular drinking and dining location today.
