Luarca (Ḷḷuarca in Asturian and coofficially[1]) is a parish and the principal town in the municipality of Valdés in Asturias, Spain.

San Timoteo festivities usually attract thousands of people every August.

Museo del Calamar Gigante, said to be the world's only museum dedicated to the giant squid, was based in the town from its opening in 2010 to its destruction by a storm in 2014; it reopened at a new location in the centre of town in 2022.

The Way of St. James named The Northern Way (Camino de la Costa) passes Luarca.

The town experiences warm summers and relatively mild winters, but strong storms occur in autumn.
