Branchport is a hamlet in the town of Jerusalem in Yates County, New York, United States.

The name "Branchport" comes from its location at the north end of the west branch of the Y-shaped Keuka Lake.

Branchport became an important port for steamboats which plied the waters of Keuka Lake carrying both passengers and produce from 1835 to 1922.

It was also the western terminus of the Penn Yan, Keuka Park and Branchport railway, an 8+1⁄2-mile electric trolley which provided passenger and freight car service from 1913 to 1928.

As transportation became more available and industry became concentrated in larger towns, Branchport became largely a residential community, but continues to serve an area of summer lake residents and tourists, as well as farmers who are mainly involved in the growing of grapes.
