Mateikonys is a village in the Šalčininkai district municipality, Lithuania near the border with Belarus. According to the 2001 census it had population of 177.
From 1923 to 1939 the village was located in Wilno Voivodeship, north-east Second Polish Republic. After the Nazi German and Soviet invasions of Poland in September 1939 the village was transferred to Lithuania according to the Soviet–Lithuanian Mutual Assistance Treaty.
During the Nazi occupation of Matejkany, one of its Polish defenders, Captain Stanisław Truszkowski adopted Estera Bielicka, a Jewish girl, passing her off as his own child. She was of the same age as his daughter and lived "in plain sight of all of the residents of this village. Not only did the villagers know about her, but she was also seen at church services in town and no one from among the parishioners betrayed her."
