The Rotuaari is a pedestrian zone in the Pokkinen district in Oulu, Finland.

The area, together with the Oulu Market Square, is being managed by the Oulu City Centre Shopkeeper Association (Finnish: Oulun Liikekeskus ry).

The name of the zone was derived from the French word trottoir.

The main square of the zone is the Oulu Central Square (Finnish: Oulun Keskusaukio), where most of the festivals and other events of Rotuaari are held.

In 2012, a heating system was placed under the whole length of the pedestrian part of Kirkkokatu (including the Central Square), so that it will be free of ice and snow during the winter months.
