Matugama is an electorate in the district of Kalutara in Sri Lanka. It is located 64 km to the south of Colombo.
Matugama is part of the Pasdun Korale ('County of the five yojanas'), created when King Parakramabahu the Great drained the Kalu Ganga basin. In the days of the State Council it comprised the present-day Agalawatte, Bulathsinhala and Matugama constituencies. In 1946, it was divided into two, the eastern portion becoming Agalawatte (itself subdivided in 1960 by the creation of Bulathsinhala).
