The African dusky flycatcher (Muscicapa adusta), also known as the dusky-brown flycatcher or dusky alseonax, is a small passerine of the Old World flycatcher family, Muscicapidae. It is usually found along forest edges and in wooded areas in the highlands of Africa from Nigeria, the Central African Republic, South Sudan and Ethiopia south to South Africa. Its upperparts are plain brown, with the only facial marking being an indistinct narrow eye-ring.
