Malestroit (French pronunciation: [maletʁwa]; Breton: Malastred) is a commune in the Morbihan department of Brittany in north-western France.

[4] Malestroit is on the Nantes-Brest canal, which is no longer completely navigable.

However, the section through the town is over 200 km long, and barges moor up near the centre of Malestroit.

The nearby village of Saint-Marcel houses a museum dedicated to the Breton Resistance movement where a battle against the Nazis took place and was won by the Resistance fighters.

[6] Malestroit, whose inhabitants are known in French as Malestroyens, is twinned with the town of Jedburgh in the United Kingdom.
