Slidre is a former municipality in the old Oppland county, Norway.

The administrative centre was the village of Slidre.

[5] The prestegjeld of Slidre was established as a civil municipality on 1 January 1838 (see formannskapsdistrikt law).

[6] The municipality (originally the parish) is named after the old Slidre farm (Old Norse: Slíðrar or Slíðrir) since the historic Slidre Church was built there during the 12th century.

It may be derived from the word slir which comes from the Old Norse word slíðr which means "sheath" (which is probably referring to a long depression near the church).
