Nester House, also known as Geneva-on-the-Lake, is a historic home located at Geneva in Ontario County, New York, USA.

The Renaissance Revival building's design is based upon the Villa Lancellotti, a 16th-century suburban villa in the village of Frascati near Rome.

In 1973, the Capuchins sold the property and the house and its 1949 additions were later converted into 30 apartments.

It was listed on the National Register of Historic Places in 1984.
