The Merchants and Drovers Tavern is located at 1632 Saint Georges Avenue in the city of Rahway in Union County, New Jersey, United States.

An analysis of samples of the building's wooden frame conducted by Columbia University's Lamont Dougherty Earth Sciences Observatory found that there were two distinct periods of construction – one in 1795–1796, then another in 1818–1819.

The claim that the building did not exist until 1795 at the earliest is further supported by the fact that the first innkeeper, John Anderson, did not receive a tavern license until 1798, after the initial period of construction.

The Merchants and Drovers Tavern Museum Association (MDTMA) runs historic tours and talks, including on the Victorian-era murder known as The Unknown Woman or Rahway Jane Doe.

In 2017, the cast of the hit paranormal reality series Ghost Hunters held a fundraiser for the museum.
