The Magellanic Horned Owl or Lesser Horned Owl ("Bubo magellanicus") is a large owl of the genus "Bubo" found in southern South America. It was formerly classified as a subspecies of the Great Horned Owl ("Bubo virginianus") but is now frequently treated as a separate species based on differences in voice and size and because of the genetic distance between the two.

It is about 45 centimetres long with birds in the north of the range being largest. It has broad wings and a large head with two "ear" tufts. The plumage is mainly grey-brown but is quite variable in colour. The underparts are pale with narrow grey-brown bars and the breast has dark blotches. There is a black border to the facial disc and white stripes above the yellow eyes. The Great Horned Owl is similar but larger with stronger feet and bill, broader bars on the underparts and longer ear-tufts.

The deep hooting call consists of a double-note followed by a loud, vibrating note. The bird's local name "tucúquere" is imitative of the call.

The range extends from central Peru and western Bolivia southwards through Chile and western Argentina as far as Tierra del Fuego. The bird occurs in a variety of habitats including open forest, scrubland, farmland and grassland. It hunts over open country, mainly at night. Rodents make up most of the diet but birds and insects are also taken.
