The municipality had a population of 5,230 (1963) and covered a land area of 606.1 square kilometres (234.0 sq mi).

Its neighbouring municipalities were Kempele, Kiiminki, Muhos, Oulu, Tyrnävä, Utajärvi and Ylikiiminki.

The municipality of Oulujoki was dissolved in 1965, and its area was annexed to Haukipudas, Kempele, Kiiminki, Oulu, Oulunsalo, Tyrnävä, Utajärvi and Ylikiiminki.

Its initial name was Oulun maalaiskunta, but it was renamed Oulujoki after the Oulu River in 1910.

[3] In 2006, a group of locals led by Paavo Vasala made a proposition to separate the old Oulujoki municipality from Oulu, stating that the town's government has been neglecting the area due to earlier conflicts between the town and the local land owners over the usage of the lands.
