Mikasa (三笠市, Mikasa-shi) is a city located in Sorachi Subprefecture, Hokkaido, Japan. As of 1 October 2020, the city has an estimated population of 8,040, and the density of 27 persons per km.

The total area is 302.64 km. It is bordered on three sides by mountains, and on its east side is the man-made Lake Katsurazawa.

Mikasa is one of the birthplaces of the mining and railroad industries in Hokkaido, and the Hokkai Bon song was invented there. Though in the past it flourished due to its natural abundance of coal, the mines have largely closed down and this has caused the population of the city to fall rapidly.

Quite a few fossil specimens have also been collected there, particularly ammonites and the prehistoric marine reptile Yezosaurus mikasaensis, both of which can be viewed at the city's natural history museum.
