The Ostrobothnian Plain or Pohjanmaa is a large lowland in Finland along the Bothnian Sea being arguably the largest plain in the Nordic countries.[1] The plain is made up smaller individual sand and clay plains alternated with rivers and peat bogs.[2] It extends as a 100 km wide and 257 km long belt along the northwestern coast of Finland.[1][2] The plain is extremely flat with height differences never exceeding 50 m.[1]

Geologically the plain is a continuation of the Sub-Cambrian peneplain found across much of Fennoscandia.[3]
