Brân the Blessed (Welsh: Bendigeidfran or Brân Fendigaidd, literally "Blessed Raven") is a giant and king of Britain in Welsh mythology. He appears in several of the Welsh Triads, but his most significant role is in the Second Branch of the Mabinogi, Branwen ferch Llŷr. He is a son of Llŷr and Penarddun, and the brother of Brânwen, Manawydan, Nisien and Efnysien. The name "Brân" translates from Welsh as "Raven".

The Irish king Matholwch sails to Harlech to speak with Bran the Blessed high king of the Island of the Mighty and to ask for the hand of his sister Branwen in marriage, thus forging an alliance between the two islands. Bendigeidfran agrees to Matholwch's request, but the celebrations are cut short when Efnisien, a half-brother to the children of Llŷr, brutally mutilates Matholwch's horses, angry that his permission was not sought in regards to the marriage. Matholwch is deeply offended until Bran offers him compensation in the form of a magic cauldron that can restore the dead to life. Pleased with the gift, Matholwch and Branwen sail back to Ireland to reign.
