Dorothy is an unincorporated community[2] in Section 5, Louisville Township, Red Lake County, Minnesota, United States.

Dorothy was initially established as a railroad station in 1916–17, after the Northern Pacific Railway extended its line from Tilden Junction to Winnipeg and built a spur through Red Lake Falls.

The post office in Dorothy was first established February 11, 1898, with Joseph H. Mathews as postmaster.

[3] The Federal Writers' Project reported in 1938 that the town had a population of 25, and "a beautiful church with stained-glass windows".

On October 24, 2014, the old church caught fire and burned to the ground in a conflagration that apparently started after embers from a pile of leaves a property owner was burning nearby blew towards the building, igniting the structure, which was a total loss.
