Waternish or Bhatairnis/Vaternish is a peninsula approximately 12 km (7.5 mi) long on the island of Skye, Scotland, situated between Loch Dunvegan and Loch Snizort in the northwest of the island, and traditionally inhabited and owned by Clan MacLeod whose clan seat is at the nearby Dunvegan Castle. The current clan chief is Hugh Macleod of Macleod. It contains the hamlets of Stein and Lusta in Loch Bay to the south east, Halistra, Hallin and Trumpan further north and Gillen to the west, all of which are accessed from the A850 road by crossing the Fairy Bridge. The highest point is Ben Geary (284 m (932 ft)) and the most northerly is Waternish Point. The name Waternish is derived from the Norse vatnenes or "headland of the pond".
The history of the peninsula is a long (and often bloody) one involving clan feuds, massacres, de-population during the Highland Clearances, and eventual re-vitalisation. Originally consisting of small crofting communities, Waternish now has a growing population and is home to various arts and crafts enterprises. Whilst the main industry on Waternish is tourism, there has also been a revival in recent years of crofting or small scale agriculture. The local school is called Knockbreck. The school has struggled recently due to an ageing population which has resulted in only 4 students currently attending. The local pub is the Stein Inn, which dates back to 1790 and is the oldest on Skye.
