Orosh Abbey (also known as Mirditë Abbey or St. Alexander Oroshi) was a territorial Benedictine abbey in Orosh, Albania, now destroyed, dedicated to the martyr St. Alexander. By papal decree of 25 October, 1888, this abbey with its two affiliated parishes, together with five other parishes in the Diocese of Lezhë (Alessio, Lješ) were removed from the jurisdiction of the Bishop of Lezhë. In 1890 three parishes from the Diocese of Sapë were added, and in 1894 five more parishes from Lezhë.
