William LaBarthe Steele (May 2, 1875 – March 4, 1949) was an American architect from Chicago, Illinois. He is considered a principal member of the Prairie School Architectural Movement during the early 20th century.

Career After graduating from the University of Illinois, Steele worked under renowned architect Louis Sullivan in Chicago, Illinois, from 1897 to 1900. He later moved to Pittsburgh, Pennsylvania, where he worked at several firms.

In 1904, he settled in Sioux City, Iowa, where he stayed for 25 years until moving to Omaha, Nebraska, in 1929. Around this time, he and Thomas Rogers Kimball founded an architectural firm that eventually became Steele, Sandham, and Steele."

The Woodbury County Courthouse in Sioux City is considered to be a premier example of Prairie School aesthetics, which he developed along with Minneapolis-based architects George Grant Elmslie and William Gray Purcell. All three men had previously worked for Sullivan in various roles. The Courthouse, along with Walthill Hospital in Nebraska (1912), are both designated National Historic Landmarks. Over 20 of his surviving works are on the National Register of Historic Places (NrHP).
