The brown-streaked flycatcher (Muscicapa williamsoni) is a species of bird in the family Muscicapidae.

[1] Some authorities consider it to be a subspecies of the Asian brown flycatcher.

In 2020, a vagrant was sighted 300 km (190 mi) south of the Australian town of Broome and its identity was confirmed from DNA analysis of the droppings of the bird.

[2] The species has a rufescent plumage in the breeding season and then becomes drab.

[3] The species name is after the collector Sir Walter James Franklin Williamson.
