Isle Ristol, the innermost of the Summer Isles in Scotland, is a Scottish Wildlife Trust Reserve.

Lying roughly {{convert|12|mi|km|abbr=off}} north of Ullapool in Wester Ross, it is a tidal island, in Loch an Alltain Duibh, that is separated by a narrow channel from Old Dorney Bay. Access is by boat from Old Dornie.

Over fifty higher species have been identified amongst the flora on the Isle Ristol machair, amongst which are moonwort and adder's tongue.{{cite web|title=SWT Reserve: Isle Ristol |url=http://www.swt.org.uk/wildlife/popup_reserves/north/isleristol.htm |access-date=2007-07-16 |archive-url=https://web.archive.org/web/20070714132948/http://www.swt.org.uk/wildlife/popup_reserves/north/isleristol.htm |archive-date=14 July 2007 |url-status=dead }}
