Dolavon (Welsh: Dolafon) is a small town in the Patagonian province of Chubut, Argentina.

It is located close to the Chubut River, about 19 km (12 mi) to the west of Gaiman.

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.

According to plans announced in November 2006,[needs update] Dolavon was to be the site of important energy generation facilities by mid-2008: a combined cycle power plant (with an output of between 330 and 465 MW) and a wind farm (100 MW).
