Pontresina (Romansh: Puntraschigna) is a municipality in the Maloja Region in the canton of the Grisons in Switzerland .

Pontresina was first mentioned in medieval Latin documents as ad Pontem Sarisinam in 1137 and de Ponte Sarraceno in 1237. The name consists of the Latin word for bridge, pons (accusative form: pontem), and the male personal name Saracenus, which was widely known in the Engadin valley. The earlier assumption that the name was connected with the Saracens has been discarded.

Pontresina owes its importance to its location on the Bernina Pass and to tourism. In the Middle Ages, the place was more important than neighbouring St.
