The Frank W. Thomas House is a historic house located at 210 Forest Avenue in Oak Park, a suburb of Chicago in Illinois, United States. The building was designed by architect Frank Lloyd Wright in 1901 and cast in the Wright-developed Prairie School of Architecture. By Wright's own definition, this was the first of the Prairie houses - the rooms are elevated, and there is no basement. The house also includes many of the features which became associated with the style, such as a low roof with broad overhangs, casement windows, built-in shelves and cabinets, ornate leaded glass windows and central hearths/fireplaces. Tallmadge & Watson, a Chicago firm that became part of the Prairie School of Architects, added an addition to the rear of the house in 1923.{{cite web|last1=Bell|first1=Robert A.|title=National Register of Historic Places Inventory - Nomination Form: Frank Thomas Residence|url=http://gis.hpa.state.il.us/pdfs/200508.pdf|archive-url=https://web.archive.org/web/20160415053007/http://gis.hpa.state.il.us/pdfs/200508.pdf|url-status=dead|archive-date=April 15, 2016|publisher=Illinois Historic Preservation Agency|access-date=April 2, 2016|date=July 4, 1972}}
