The Accession Day tilts were a series of elaborate festivities held annually at the court of Elizabeth I of England to celebrate her Accession Day, 17 November, also known as Queen's Day. The tilts combined theatrical elements with jousting, in which Elizabeth's courtiers competed to outdo each other in allegorical armour and costume, poetry, and pageantry to exalt the queen and her realm of England.
The last Elizabethan Accession Day tilt was held in November 1602; the queen died the following spring. Tilts continued as part of festivities marking the Accession Day of James I, 24 March, until 1624, the year before his death.
Sir Henry Lee of Ditchley, Queen's Champion, devised the Accession Day tilts, which became the most important Elizabethan court festival from the 1580s. The celebrations are likely to have begun somewhat informally in the early 1570s. By 1581, the Queen's Day tilts "had been deliberately developed into a gigantic public spectacle eclipsing every other form of court festival", with thousands in attendance; the public were admitted for a small charge. Lee himself oversaw the annual festivities until he retired as Queen's Champion at the tilt of 1590, handing over the role to George Clifford, 3rd Earl of Cumberland. Following Lee's retirement, orchestration of the tilts fell to the Earl of Worcester in his capacity of Master of Horse and to the queen's favourite, the Earl of Essex, although Lee remained as a sort of Master of Ceremonies at the request of the queen.
