Ronas Hill (Old Norse: rön, meaning stony ground or scree) is on the Northmavine peninsula of Mainland, Shetland, at HU305835.

[citation needed] The hill forms part of the Ronas Hill – North Roe and Tingon Important Bird Area (IBA), designated as such by BirdLife International because it supports a suite of moorland-breeding birds, including red-throated loons, great skuas and merlins.

Most surviving Neolithic British cairns are sited in prominent places, but not generally on the top of taller hills.

Ronas Hill cairn shows evidence of substantial rebuilding of its upper structure, as evidenced by the lack of lichen on stones above the entry passage and main cyst.

The current peak of pink granite stones is clearly visible from the valley below and may have been raised in height to serve as a "mede" or fishing mark in past centuries.
