Olivet (French pronunciation: [ɔlivɛ], [ɔlive] ⓘ) is a commune in the department of Loiret, north-central France.

Olivet belongs to the Loire Valley sector between Sully-sur-Loire and Chalonnes-sur-Loire, which was in 2000 inscribed by UNESCO as a World Heritage Site.

Olivet is crossed by the Loiret, a 13 km long river which is both a tributary and a resurgence of the Loire.

The peaceful river Loiret, surrounded by trees and home of numerous swans, offers pleasant public walks.

On the north side of the main bridge, the Horloge fleurie is a giant clock on a flowery slope.
