The Mansion House in York, England is the working residence of the Lord Mayors of York during their term in office. It is situated in St Helen's Square, where York's Coney Street and Lendal intersect in the city centre. It is built in an early Georgian style. The Mansion House is the earliest purpose-built house for a Lord Mayor still in existence, and predates the Mansion House in London by at least twenty years.

The foundation stone for the Mansion House was laid in 1725, with the building being completed seven years later in 1732. The architect who designed the Mansion House is unknown, although the frontage may be by William Etty.
