Gibbon's Tennis Court was a building off Vere Street and Clare Market, near Lincoln's Inn Fields in London, England. Originally built as a real tennis court, it was used as a playhouse from 1660 to 1663, shortly after the English Restoration. As a theatre, it has been variously called the "Theatre Royal, Vere Street", the "Vere Street Theatre", or (as in Samuel Pepys' diary) simply "The Theatre". It was the first permanent home for Thomas Killigrew's King's Company and was the stage for some of the earliest appearances by professional actresses. The London School of Economics, which covers most of Clare Market nowadays, retains some squash and real tennis courts in its older buildings.
Tudor-style real tennis courts were long, high-ceiling buildings, with galleries for spectators; their dimensions — about 75 by 30 feet — are similar to the earlier theatres, and much larger than a modern tennis court. The tennis courts were not used exclusively for tennis. In 1653, seven years before it saw lawful use as a theatre, an underground production of Killigrew's Claricilla was planned for Gibbon's court. The production was broken up before it debuted, reportedly betrayed to the army by one of the actors.
After the English Restoration in 1660, Charles II granted Letters Patent to two companies to perform "legitimate drama" in London: the Duke's Company under the patronage of the Duke of York, led by William Davenant, and the King's Company, led by Thomas Killigrew. Both companies briefly performed in the theatrical spaces that had survived the interregnum and civil war (including the Cockpit and the Red Bull), but scrambled to quickly acquire facilities that were more to current tastes. Killigrew and Davenant both chose a solution that had been used in France: converting tennis courts into theatres.
