The Daniel Robert House is a historic house located at 25 West End Avenue in the borough of Somerville in Somerset County, New Jersey.

The house was built in 1888 for Daniel Robert (1840–1908) by the architectural firm Lambert & Bunnell based on Gothic Revival style houses designed by the architect Alexander Jackson Davis.

The building was added to the National Register of Historic Places on March 5, 2008 for its significance in architecture from 1888 to 1939.

Daniel Robert, a wealthy businessman from New York, bought the property in 1886.

He tore down the Cammann house in 1887 and built the current mansion.
