Kookaburras (pronounced ) are terrestrial tree kingfishers of the genus Dacelo native to Australia and New Guinea, which grow to between 28 and 47 cm (11 and 19 in) in length and weigh around 300 g (11 oz). The name is a loanword from Wiradjuri guuguubarra, onomatopoeic of its call. The loud, distinctive call of the laughing kookaburra is widely used as a stock sound effect in situations that involve an Australian bush setting or tropical jungle, especially in older movies.

They are found in habitats ranging from humid forest to arid savannah, as well as in suburban areas with tall trees or near running water. Though they belong to the larger group known as "kingfishers", kookaburras are not closely associated with water.
