The Cleveland Cavaliers (often referred to as the Cavs) are an American professional basketball team based in Cleveland. The Cavaliers compete in the National Basketball Association (NBA) as a member of the league's Eastern Conference Central Division.

The team began play as an expansion team in 1970, along with the Portland Trail Blazers and Buffalo Braves. Home games were first held at Cleveland Arena from 1970 to 1974, followed by the Richfield Coliseum from 1974 to 1994. Since 1994, the Cavs have played home games at Rocket Mortgage FieldHouse in downtown Cleveland, which is shared with the Cleveland Monsters of the American Hockey League.

In 2016, the Cavaliers won their first NBA Championship, marking Cleveland's first major sports title since 1964. The 2016 NBA Finals victory over the Golden State Warriors marked the first time in Finals history a team had come back to win the series after trailing three games to one. The Cavaliers have made 22 playoff appearances, and won seven Central Division titles, five Eastern Conference titles, and one NBA title.
