Shikaoi (鹿追町, Shikaoi-chō) is a town located in Tokachi Subprefecture, Hokkaido, Japan.

A big role was played for industrial development of Shikaoi by the upgrading a network of roads and railway.

The population increased rapidly by the settlement of Japan Self-Defense Forces Stationing Grounds after the World War.

After a peak population of 10,778 people in 1961, it decreased gradually by the influence of cold-weather damage to agriculture.

In 1984, Shikaoi began a sister town relationship with Stony Plain, Alberta, Canada.
