Pickleball is an indoor or outdoor racket/paddle sport where two players (singles), or four players (doubles), hit a perforated hollow plastic ball over a 36-inch-high (0.91 m) net using solid-faced paddles. Opponents on either side of the net hit the ball back and forth until one side commits a rule infraction. Pickleball was invented in 1965 as a children's backyard game on Bainbridge Island, Washington, US. In 2022, pickleball was adopted as the official state sport of Washington.

The appearance of a pickleball court, and the manner of play, resembles tennis, but the court is the size of a doubles badminton court, less than a third the size of a tennis court. Court lines and rules are specific to pickleball and include two 7-foot areas (2.1 m) on either side of the net known as the non-volley zones, where the ball cannot be hit with the paddle unless the ball bounces first. The official rules specify side-out scoring, where only the serving team can score a point. All serves are made with an underhand stroke. The hard plastic ball used in pickleball produces significantly less bounce than softer flexible balls, such as a tennis ball. The minimal bounce combined with the non-volley zone and underhand serve give the game dynamic pace and strategy ranging from soft dink shots that stay within the two non-volley zones to powerful drive shots and overhead smash shots. To minimize any advantage the serving or receiving side might have at the beginning of the game, the ball must bounce once on each side of the net before either team may volley the ball, which is to hit the ball in the air before it bounces.

Between 1965 and 2020, it became a popular sport in the US Pacific Northwest, and in the meantime began to grow elsewhere. In 2021, 2022 and 2023, the sport was named the fastest-growing sport in the United States by the Sports and Fitness Industry Association, with over 4.8 million players. A growing interest in the sport is attributed to several factors, including a short learning curve, appeal to a wide range of ages and fitness levels, and low startup costs. There are now thousands of pickleball tournaments throughout the United States, including the US National Championships and the U.S. Open Tournament, along with two professional tours and one professional league. Pickleball is also experiencing growth outside the United States with several other national and international competitions.
