The forest around Thorp was Ojibwe (Chippewa) territory in the decades before white settlers arrived. In the 1837 Treaty of St. Peters, the Ojibwe ceded Thorp and much of northern Wisconsin to the U.S. Around 1837 a sawmill and settlement began in Chippewa Falls to the west. In 1844 James O'Neill settled at Neillsville to the south. From 1847 to 1853 surveyors for the U.S. government marked off the section lines that would become Thorp and assessed timber and land quality.
