Vågå (Norwegian pronunciation: [ˈʋoːˈɡoː]) is a municipality in Oppland county, Norway. It is part of the traditional region of Gudbrandsdal. The municipality comprises 1,330 km². The administrative centre is the village of Vågåmo.

The parish of Vaage was established as a municipality on 1 January 1838 (see formannskapsdistrikt). The areas of Sel and Heidal were separated from the municipality of Vågå to become separate municipalities of their own on 1 January 1908.

Two origins have been suggested for the name Vågå:

Prior to 1918, the name was written "Vaage". In 1918, it was changed to "Vaagaa" and in 1921 the spelling was again changed to "Vågå". The letter å is a long vowel similar to "oh" or "aw", like in the American pronunciation of "cold" or "oar."

The coat-of-arms is from modern times. They were granted on 23 August 1985. The arms show a gold reindeer on a red background. They are based on a character in Henrik Ibsen's book Peer Gynt, who rides on a reindeer bull over the Besseggen mountains. Ibsen got the idea for this book from a local story.

Vågå is bordered on the north by the municipality of Lesja, in the east by Dovre and Sel, in the southeast by Nord-Fron, in the south by Vang and Øystre Slidre, and in the West by Lom.
