The Brahan Seer, known in his native Scottish Gaelic as Coinneach Odhar ("Dark Kenneth"), and Kenneth Mackenzie, was, according to legend, a predictor of the future who lived in the 17th century.

The Brahan Seer is regarded by some to be the creation of the folklorist Alexander MacKenzie (1838–1898) whose accounts occur well after some of the events the Seer is claimed to have predicted.
