Joseph Ellicott Historic District is a local historic district in Buffalo, New York. It is in the vicinity of Niagara Square, which was designed by Joseph Ellicott as the centerpiece of the city's street plan in 1805.

The district was founded on November 30, 1982, by the Buffalo Preservation Board. It is bordered to the North by West Mohawk Street, to the East by Franklin Street, to the South by Swan Street, and to the West by Elmwood Avenue.

Sahlen Field encroached on the southern border of the district when it was built in 1988, although the Buffalo Preservation Board approved the venue's construction after the architecture was designed to match the neighboring Ellicott Square Building and Old Post Office.
