Dolavon (Welsh: Dolafon) is a small town in the Patagonian province of Chubut, Argentina. It has a population of 2,929 according to the 2001 census [INDEC]. It is located close to the Chubut River, about 19 km to the west of Gaiman. The name comes from Welsh dôl (meadow) and afon (river). Welsh immigrants began to settle in the area after their arrival in Patagonia in 1865. The Central Chubut Railway arrived in 1915, linking the settlement to Trelew, and the town was officially founded in 1919. Dolavon became a centre of wheat production using irrigation canals to compensate for the arid climate. The old flour mill with its water wheel is now a museum.
