Other villages in the municipality include Hegge, Rogne, Volbu, Moane, Skammestein, Beito, and Beitostølen.

The municipality (originally the parish) is named after the old Slidre farm (Old Norse: Slíðrar) since the old Slidredomen church was built there.

The name is probably derived from the word slíðr which means "sheath" (which is probably referring to a long depression near the church).

The official blazon is "Plumetty azure and argent" (Norwegian: Dekt av blå og sølv skjell).

According to local folklore, the dispute began in medieval times with a young bride being married to an old man and a knight stealing his way over the mountains to rescue her.
