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 rebuilt in 1714, and used again as a theatre for a third period, 1714–1732. 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.

Lincoln's Inn Fields is the largest public square in London. It was laid out in the 1630s under the initiative of the speculative builder and contractor William Newton, "the first in a long series of entrepreneurs who took a hand in developing London", as Sir Nikolaus Pevsner observes. The original plan for "laying out and planting" these fields, drawn by the hand of Inigo Jones, was said still to be seen in Lord Pembroke's collection at Wilton House in the 19th century, but its location is now unknown. The grounds, which had remained private property, were acquired by London County Council in 1895 and opened to the public by its chairman, Sir John Hutton, the same year. The square is today managed by the London Borough of Camden and forms part of the southern boundary of that borough with the City of Westminster.
