Brandivy (French pronunciation: [bʁɑ̃divi]; Breton: Brandevi) is a commune in the Morbihan department of Brittany in northwestern France.

Brandivy is notable for its "Breizh – Kernow Festival" (Breizh = Brittany in Breton; Kernow = Cornwall, United Kingdom, in the Cornish language) which takes place at Easter.

The Breizh – Kernow Festival now occurs on odd numbered years (2003, 2005, 2007) and AberFest on even numbered years (2004, 2006 and due at Easter 2008).

In recent years, Brandivy has shared festival events with Bignan.

This has developed to create very close, international family links between participants in Cornwall and Brittany which now spread over more than 20 years.
