Languidic (French pronunciation: [lɑ̃ɡidik]; Breton: Langedig) is a commune in the Morbihan department of Brittany in north-western France.

The local church was previously associated with the cult of the Welsh saint Cenydd (Kenneth).

Languidic, encompassing 10,908 hectares, is the most spread-out city in Morbihan and the third in Brittany. The river Ével forms part of the commune's north-eastern border, then flows into the Blavet, which forms its northern and north-western borders.

Inhabitants of Languidic are called in French Languidiciens.
