Mousiotitsa (Greek: Μουσιωτίτσα) or Kato Mousiotitsa (Greek: Κάτω Μουσιωτίτσα) is a village located in the Ioannina regional unit in the Epirus region (Greek: Ήπειρος) of western Greece. Situated 33 km south of the city of Ioannina (Greek: Ιωάννινα) near the springs of the river Louros (Greek: ποταμός Λούρος), the village consists of 4 areas: Kato Mousiotitsa (Greek: Κάτω Μουσιωτίτσα), Ano Mousiotitsa (Greek: 'Ανω Μουσιωτίτσα), Nea Mousiotitsa (Greek: Νέα Μουσιωτίτσα) and Mesoura (Greek: Μεσούρα). It surrounded by 5 mountains, Bitera (Greek: Μπιτέρα), Spithari (Greek: Σπιθάρι), Pourizi (Greek: Πουρίζι), Kalogeritsa (Greek: Καλογερίτσα) and Katafi (Greek: Καταφή).
The origins of the name Mousiotitsa (Greek: Μουσιωτίτσα) are unknown. It has been speculated by scholars that the name is of Slavic origin due to its conspicuous ending of "-itsa", a common occurrence in Slavic settlement names. Other more local theories state that the name is derived from old myths of ancient river dwellers known as "Mouses" (Greek: Mούσες) or from a queen who resided in what is now the ruins of a castle dating back to the 3rd century AD.
It is widely regarded to have been settled in the early 18th century. The old St Nicholas church is first mentioned in the Greek church archives in the year 1791. The village is believed to have belonged to the group of villages that made up the Souli (Greek: Σούλι) mountain settlement.
On July 25, 1943, followed by 27 August 1943, German SS troops entered the village and executed a total of 153 civilians. The attack and resulting massacre was a retaliation by the Nazi German troops against alleged resistance activity in the village, and that it had supported a deadly attack on a German officer in the nearby area of Zita.
