Rutland House was the name of at least three London houses occupied by the Earls and Dukes of Rutland. That on Aldersgate Street was leased by playwright Sir William Davenant, who converted a room of it into a private theatre in the 1650s. That in Knightsbridge was a six-acre site until its demolition in the 1830s. The third is located on Park Place in St James's.
