Brenish (Scottish Gaelic: Brèinis) is a small village situated on the west coast of the Isle of Lewis, which is part of the Outer Hebrides of Scotland. It is in the district of Uig, Lewis. The name of the village is sometimes spelt Breanish (which is generally the spelling used locally), however maps normally refer to Brenish.
It is commonly regarded as one of the more scenic areas on the island, although its remote location at the end of the winding and decaying C39 makes it one of the less visited. The village itself runs parallel to the Atlantic coastline and is overlooked by Mealisval, the tallest mountain on the island. It is located next to the village of Mealista which is an uninhabited village known best for its selection of virginal sandy beaches. Mealista is where the road ends, making Brenish the last populated village on the C39.
