The Lumber Exchange Building was the first skyscraper built in Minneapolis, Minnesota, United States, dating to 1885.

The partnership of Long and Kees, lasting from 1884 to 1897, was particularly successful and led to the construction of many of the largest buildings in the city in the 1880s and 1890s.

Other buildings by these partners included the Public Library (1884), Masonic Temple (1888) (now the Hennepin Center for the Arts), Flour Exchange (1893–1897), Minneapolis City Hall (1889), and the Kasota Block (1884).

James Lileks, Minneapolis writer and architectural critic, says, It's one of the few survivors from the early skyscraper era – and perhaps the ugliest.

"[5]The Lumber Exchange Building was listed on the National Register of Historic Places in 1983.
