Malesia (Macedonian: Малеcија, romanized: Malesija, Albanian: Malësia; also Struga Malesia, Macedonian: Струшка Малесија, romanized: Struška Malesija, Albanian: Malësia e Strugës) is a small region in Upper Struga Municipality, in western North Macedonia, at the Golema River.
It is inhabited by Orthodox Christians, as opposed to the settlements to the south, which are Muslim.
The Karaorman Mountain is situated to the east of Ržanovo.
The toponym Malesija is of Albanian origin from the word Malësi meaning a mountainous area or region.
In a 1903 document by the Cartographic Society of Sofia, the villages of Malesia were all registered with Albanian Orthodox majorities, but nowadays they identify as Macedonians.
