The caber toss is a traditional Scottish athletic event in which competitors toss a large tapered pole called a "caber" (/ˈkeɪbər/). It is normally practised at the Scottish Highland Games. In Scotland, the caber is usually made from a larch tree and it can be between 16–20 feet (5–6 metres) tall and weighs 90–150 pounds (40–70 kilograms). The term "caber" derives from the Gaelic word cabar, which refers to a wooden beam.

The person tossing the caber is called a "tosser" or a "thrower".

It is said to have developed from the need to toss logs across narrow chasms (in order to cross them), lumberjacks needing to transport logs by throwing them in streams, or by lumberjacks challenging each other to a small contest. Although the sport is primarily associated with Scotland, a similar exercise, "casting the bar", was popular in England in the 16th century, and similar sports exist around the world, such as stångstörtning in Sweden.

The record for most caber tosses in three minutes is currently held by the Canadian Danny Frame. He managed to perform 16 successful caber tosses on 20 July 2018 at the Heart of the Valley Festival in Middleton, Nova Scotia, Canada.
