The village is located along the Slidrefjorden in the Valdres district.

The village is located along the European route E16 highway, about 25 kilometres (16 mi) northwest of Fagernes.

[1] Slidre is the site of the Slidredomen, a medieval era stone church.

[3] The municipality (and the parish) were named after the old Slidre farm (Old Norse: Slíðrar or Slíðrir) since this was the location of the first Slidre Church that was built during the 12th century.

It could be derived from the word slir which means the narrow depression through which a river runs.
