Guardiola de Berguedà is a municipality in the comarca of the Berguedà in Catalonia. It is situated at the confluence of the Bastareny and Llobregat rivers in the north of the comarca. It is an important local commercial centre, and for this reason has been less affected by depopulation than other municipalities in the Berguedà. The extraction of lignite is also important to the local economy. The town is served by the C-1411 road from Berga to the Cadí tunnel, and is linked to La Pobla de Lillet and Castellar de n'Hug by the B-402 road. The municipality includes a large exclave to the north-west.
