The ground tyrants (Muscisaxicola) are a genus of passerine birds belonging to the tyrant flycatcher family Tyrannidae. There are about 13 different species. They are ground-dwelling birds which inhabit open country in South America, particularly the Andes and Patagonia. Several southern species are migratory, moving northward for the winter. Ground tyrants feed on insects and other invertebrates, mainly by picking them from the ground.

A flight display is performed during the breeding season. The nest is a cup of twigs or grass which, in most species, is built in a burrow, crevice or under rocks.

Ground tyrants are fairly small (13–20 cm in length) with longish legs, a slender bill and an erect posture. The plumage is dull and mainly grey or brown with paler underparts. The head is variably patterned with several species having rufous patches on the crown or white between the bill and eye. The birds have simple calls and are often silent.
