Regionally important geological and geomorphological sites (RIGS) (also known as regionally important geological sites or, especially in Wales, regionally important geodiversity sites) are locally designated sites of local, national and regional importance for geodiversity (geology and geomorphology) in the United Kingdom and Isle of Man. Depending on the decisions of the members of the local sites partnership, in some local areas locally designated sites including RIGS with substantive geological interest may now be called local geological sites (LGS).
