The Hämeenmaa-class minelayers (Finnish: Hämeenmaa-luokan miinalaiva) is a two-vessel strong class of coastal minelayers, used by the Finnish Navy.

The Finnish Navy ordered the lead ship Hämeenmaa as a replacement for the venerable minelayer Keihässalmi, while the second ship brought the number of Finnish Navy minelayers to three, complementing the slightly larger Pohjanmaa. The ships were constructed at the Rauma shipyard by Finnyards.

The ships have a steel hull and aluminum alloy superstructure. The class has an ice operating classification of ICE-1A and can operate year-round in ice up to 40 cm thick.

During a crisis the main task for the Hämeenmaa-class ships is minelaying, but the vessels can also act as escort, transport and depot ships.
