The Buru jungle flycatcher (Eumyias additus), also known as the streak-breasted jungle-flycatcher or streaky-breasted jungle-flycatcher, is a species of bird in the Old World flycatcher family Muscicapidae. It is endemic to the island of Buru in Indonesia where it originally inhabited tropical forests at elevations between 500 and 1,500 m.
This species was previously assigned to the genus Rhinomyias but was moved to Eumyias after a 2010 molecular phylogenetic study found that Rhinomyias was polyphyletic.
