Arabis alpina (Alpine rock-cress) is a flowering plant in the family Brassicaceae that grows in mountainous areas of Europe, north Africa, central and eastern Asia and parts of North America. In the British Isles, it is only known to occur in a few locations in the Cuillin Ridge of the Isle of Skye.

The stems of A. alpina grow up to 40 cm (16 inches) tall, and are topped with loose heads of white, four-petalled flowers. The leaves in the basal rosette are long, strongly toothed and clearly stalked, although the stem leaves are stalkless and clasp the stem. A stem is the main axis of a vascular plant that is divided into nodes and internodes and has one or more leaves or buds at the nodes. ...

A. alpina is supposed to have originated in Asia minor about 2 million years ago. From there it migrated twice into Eastern Africa (500,000 years ago) where it grows today on the high East African mountains in the ericaceaous belt. Another migration route lead A. alpina into Europe which was then colonizzed periglacially. In genetic terms the hihgest diversity is found in Asia minor (trnL/F, ITS). In central/northern Europe and Iceland/Greenland A. alpina seems to be quite uniform in respect to genetic data (very low genetic diversity).

There is growing interest to develop Arabis alpina as a model organism for genetics, population genetics, and molecular biology. The first genetic map has been created.
