Pohjanmaa is a former minelayer of the Finnish Navy. The sole member of her class, she was the flagship of the Finnish Navy as well as the largest naval ship in service in Finland until 2013. The ship has a Finnish-Swedish ice class 1A so she can operate all year round. During a crisis, the main task for Pohjanmaa would have been mine laying and acting as a command ship. She also acted as a school ship for the Naval Academy cadets. Part of their training includes an annual cruise abroad.

The 34-year-old Pohjanmaa was scheduled for decommissioning in late 2013. In October 2013, minelayer Hämeenmaa took over the role of flagship of the Finnish Navy.

Pohjanmaa was sold to the Finnish company Meritaito in 2016 and refitted as a survey vessel. She was renamed Pohjanmeri, Finnish for the North Sea.
