Plogonnec (French pronunciation: [plɔɡɔnɛk]; Breton: Plogoneg) is a commune and small town in the Finistère department of Brittany in north-western France.

The town is situated in a hilly area about 10 km (6 mi) inland from the fishing port of Douarnenez.

[3] At the end of the sixteenth century, the French Wars of Religion devastated the parish which was also affected by the Revolt of the Bonnets Rouges in 1675.

Particularly notable is the Chapel of Saint Théleau the evangelist which is known for its intricate sculptures and is classed as an ancient monument.

[3] Plogonnec is twinned with Llandysul in West Wales, a small town in a similar rural area.
