Toppilansaari is a neighbourhood in the Tuira area[2] in the city of Oulu, Finland.

Toppilansaari was separated from the Hietasaari district while it was rezoned to residential development in the early 2000s.

The westernmost part of the neighbourhood was the location for the Finnish Housing Fair in 2005.

The Möljä Bridge over the Toppilansalmi strait connects Toppilansaari with the Toppila neighbourhood.

The harbour has been closed for commercial traffic in 2012, but the activity has ceased since the 1990s.
