The Finnish national road 22 (Finnish: Valtatie 22; Swedish: Riksväg 22; also known as Kainuuntie, "Kainuu Road") is the main route between the major cities of Oulu and Kajaani in northern Finland.

The road is 185 kilometres (115 mi) long, and it is part of the national transport route network that connects two regions, North Ostrobothnia and Kainuu.

The Finnish Transport Agency improved the entrance section of Highway 22 in Oulu between Joutsentie and Konttisentie, with the aim of increasing traffic flow and safety.

In this contract, the section of Highway 22 between Joutsentie and Haarankangas was widened into a four-lane median road and the section between Haarankangas and Sääskensuontie was improved to a two-lane median road.
