The Latsch Building is a historic commercial property in Winona, Minnesota, United States. Once known as the Kupietz Block, it was constructed in stages from 1860 to the 1880s. It was listed on the National Register of Historic Places in 1975 (under the misspelled name Kirch/Latch Building) for having local significance in the themes of architecture and commerce. It was nominated for its transitional Gothic Revival/Italianate architecture and its former occupation by the largest of several produce wholesalers that based themselves in Winona to take advantage of the city's river and rail connections.
