Silleda is a municipality in the province of Pontevedra, in the autonomous community of Galicia, Spain.

The Serra do Candán, the mountains of Chamor, San Sebastián de Meda, and the rivers Ulla and Deza define the limits of the municipality.

Silleda is famous for its cattle and agricultural fairs, which receive their largest international attendance during the Semana Verde de Galicia (Green Week of Galicia).

It is a town in continuous growth, especially since the creation of the ring road and the industrial estate on the outskirts.

The town has cultural attractions (such as the Romanesque Monastery Carboeiro) and natural ones (for example the Fervenzas do Toxa, one of the tallest waterfalls in Spain).
