Lisle's Tennis Court was a building off Portugal Street in Lincoln's Inn Fields in London. Originally built as a real tennis court, it was used as a playhouse during two periods, 1661–1674 and 1695–1705. During the early period, the theatre was called Lincoln's Inn Fields Playhouse, also known as "The Duke's Playhouse", "The New Theatre" or "The Opera". The building was demolished and replaced by a purpose-built theatre for a third period, 1714–1728. The tennis court theatre was the first public playhouse in London to feature the moveable scenery that would become a standard feature of Restoration theatres.
