Joseph P. Guth (24 June 1859 – 23 April 1928) was a popular civil engineer, architect and builder in Omaha, Nebraska, starting in the 1880s.

Graduating from school in 1879, the younger Guth worked as an architect for two years and decided to emigrate to the United States.

Originally living in Cleveland, Ohio, Guth partnered with Joseph Dietrick to start an architectural firm; however, by 1891 the partnership had dissolved.

Continuing as a sole proprietor, Guth worked business blocks, breweries, factories and warehouses, fire stations, schools, single and multifamily residences, churches and halls in Omaha and across eastern Nebraska.

Guth practiced architecture until he died, aged 68, in Omaha at his 1911 Wirt Street home on 23 April 1928.
