Planken (German pronunciation: [ˈplaŋkn̩] ⓘ; dialectal: Planka)[2] is a municipality in Oberland, Liechtenstein.

The village was looted twice, first by the Swiss in 1499 when they campaigned against Frastanz and in 1799 by the French when they ousted the Austrian forces during the Napoleonic Wars.

In 1868 the village was connected to the rest of Liechtenstein via road, making it reachable for bigger carriages.

[3] The Plankner Neugrütt is a cliffy forest north of the village, separated from it by a stripe of 20m of land and surrounded by an exclave of Schaan with the same name.

[5] The other two exclaves are in the Rhine Valley: Wes is a small meadow and Riet-Äscher is a marsh, both are surrounded by territory of Schaan.

In 1579 the owners of Gafadura, Gaflonen (today: Alpzinka) and Garselli handed their former cooperative alps over to the municipality.

[9] Its most notable structure is the eighteenth-century St. Josef Chapel [de], which belongs to the parish of Schaan.
