Arnisdale (Scottish Gaelic: Àrnasdal) is a hamlet in the historic county of Inverness-shire in the local authority area of Highlands of Scotland.

[1] It lies on the north shore of Loch Hourn, around 10 miles (16 kilometres) down a single-track road from Glenelg.

At the end of the community is a large white-painted hunting lodge called Arnisdale House, built by architects Robert John Macbeth & Alexander Ross in 1898–1916.

The hamlet is most famous as the closest settlement to Camusfeàrna, the house in which Gavin Maxwell wrote the auto-biographical story of his secluded life with his pet otters, Ring of Bright Water.

Terry Nutkins (1946 – 2012) the naturalist, television presenter and author, who had in his boyhood been one of Maxwell's otter keepers, lived at the end of his life near the village.
