Wimbledon Championships

The Wimbledon Championships, commonly called Wimbledon, is a tennis tournament organised by the All England Lawn Tennis and Croquet Club in collaboration with the Lawn Tennis Association annually in Wimbledon, London. It is chronologically the third of the four Grand Slam tennis events each year, held after the Australian Open and the French Open and before the US Open. It is the oldest tennis tournament in the world and is widely regarded as the most prestigious.

Wimbledon has been held since 1877 and is played on outdoor grass courts; it is the only tennis major still played on grass, the traditional surface. It is also the only major that retains a night-time curfew, though matches can now continue until 23:00 under the lights.

The tournament traditionally takes place over two weeks in late June and early July, starting either on the last Monday in June or the first Monday in July and culminating with the Ladies' and Gentlemen's Singles Finals, scheduled for the Saturday and Sunday at the end of the second week. Five major events are held each year, with additional junior and invitational competitions also taking place. In 2009, Wimbledon's Centre Court was fitted with a retractable roof to lessen the loss of playing time due to rain. A roof was operational over No. 1 Court from 2019, when a number of other improvements were made, including adding cushioned seating, a table and 10 independently operable cameras per court to capture the games.

Wimbledon traditions include a strict all-white dress code for competitors, and royal patronage. Strawberries and cream are traditionally consumed at the tournament, in latter years accompanied by champagne. Unlike other tournaments, advertising is minimal and low-key from official suppliers such as Slazenger and Rolex. The relationship with Slazenger is the world's longest-running sporting sponsorship, providing balls for the tournament since 1902.

Due to the COVID-19 pandemic, Wimbledon 2020 was cancelled, the first cancellation of the tournament since World War II. The rescheduled 134th edition was staged from 28 June 2021 to 11 July 2021. The 135th edition was played between 27 June 2022 and 10 July 2022, and regularly scheduled play occurred in the middle Sunday for the first time. It marked the centenary of the inaugural championships staged at the Centre Court. The ATP, ITF, and WTA did not award ranking points for the 2022 tournament, due to controversy over the tournament excluding players representing Russia and Belarus.

The 2025 Wimbledon Championships will run from 30 June to 13 July. All in-person line judges will be replaced by electronic line calling systems for the first time in the tournament's 147-year history.
