Esko is an unincorporated community and census-designated place (CDP) in Thomson Township, Carlton County, Minnesota, United States.

Carlton County Road 61 serves as a main route in the community.

Most Esko residents are descendants of Finnish, Norwegian and Swedish immigrants who settled the area during the early 20th century.

In 1919, a small store was built at the corner of what is now Thomson Road and County 61 by a man named Alex Esko.

The Lincoln School was built nearby in 1920 and residents began to move into the area.
