The Mannlicher-Schönauer (also \"Mannlicher Schoenauer\") is a type of rotary magazine bolt action rifle produced by Steyr-Mannlicher for the Greek Army in 1903 and later was also used in small numbers by the Austro-Hungarian Armies.

In the late 1800s, the classic Mannlicher designs for the Austro-Hungarian army were based on the en-block magazine, a straight-pull bolt mechanism and were designed for obsolete large caliber cartridges. Following the introduction of smokeless powder in the Lebel rifle at the end of the Century, the Steyr factory worked on new Mannlicher designs, using more effective modern cartridges. These were offered for the consideration of the Austro-Hungarian Army, for export to other Armies and for the civilian market.

The military Mannlicher-Schoenauer was not commercially successful, in the sense that it did not attract many contracts for export. The unusual design and calibre, the high quality/cost and the fact that no major power adopted it, might have contributed to this fact. Most of the foreign Mannlicher clients opted instead for versions of the issue rifle of Austria-Hungary, the M1895. The Mannlicher-Schoenauer M1903 though fulfilled the specifications of the Greek Army and the first major contract was signed by the Greek Government in 1903.
