Matera is a city in the region of Basilicata, in Southern Italy.

As the capital of the province of Matera, its original settlement lies in two canyons carved by the Gravina River. This area, the Sassi di Matera, is a complex of cave dwellings carved into the ancient river canyon. Over the course of its history, Matera has been occupied by Greeks, Romans, Longobards, Byzantines, Saracens, Swabians, Angevins, Aragonese, and Bourbons.

By the late 1800s, Matera's cave dwellings became noted for intractable poverty, poor sanitation, meager working conditions, and rampant disease. Evacuated in 1952, the population was relocated to modern housing, and the Sassi (Italian for "stones") lay abandoned until the 1980s. Renewed vision and investment led to the cave dwellings becoming a noted historic tourism destination, with hotels, small museums and restaurants – and a vibrant arts community.

Known as la città sotterranea ("the underground city"), the Sassi and the park of the Rupestrian Churches were named a UNESCO World Heritage Site in 1993. In 2019, Matera was declared a European Capital of Culture.
