Kookaburras are terrestrial tree kingfishers of the genus Dacelo native to Australia and New Guinea, which grow to between 28–42 cm (11–17 in) in length. The loud distinctive call of the Laughing Kookaburra is widely used as a stock sound effect in situations that involve a jungle setting.

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

Kookaburras are almost exclusively carnivorous, eating mice, snakes, insects, small reptiles, and the young of other birds; they have also been known to take goldfish from garden ponds. In zoos, they are usually fed food for birds of prey.

Olly the Kookaburra was one of the three mascots chosen for the 2000 Summer Olympics in Sydney. The other mascots were Millie the Echidna and Syd the Platypus.
