Plouézec (French pronunciation: [pluezɛk]; Breton: Ploueg-ar-Mor) is a commune in the Côtes-d'Armor department in Brittany in northwestern France.

It has 17 km of rugged coastline that makes it a tourist destination all year round, with beaches such as Bréhec and Pors Pin.

Plouézec is twinned with the Irish town of Ballinamore and the twinning committee hosts a Fest Noz festival every August around the Moulin de Craca which regularly draws thousands of visitors.

Water-based sports such as fishing, sailing, and swimming are very popular and are practised by locals and tourists alike.

The municipality launched a linguistic plan through Ya d'ar brezhoneg on 14 November 2008.
