Arenaria norvegica, also known as Arctic, English or Norwegian sandwort, is a low growing plant in the family Caryophyllaceae, found in northwest Europe.

The midrib of the leaves is indistinct and the margins glabrous only in the lower third which distinguishes it from the rather similar Arenaria ciliata.

norvegica is found in west and northwest Scotland, the Shetland Isles, western Ireland, and Scandinavia[3] and Iceland.

[4][5] Arenaria norvegica is mentioned,[6] in Edward Forbes essay (1846) "On the Connexion between the Distribution of the existing Fauna and Flora of the British Isles and the Geological Changes which have affected their area..." in Memoirs of Geological Survey of Great Britain H.M. Stationery Office, 1846 - England, as a plant among others that shows migration from Scandinavia by means of ice flows in the Glacial Epoch of the Pleistocene.

norvegica is found on base-rich (alkaline) sandy and gravelly substrates [4] including those derived from ultrabasic igneous rocks and serpentine as well as limestone.
