George Leighton Dahl (May 11, 1894 – July 18, 1987) was a prominent American architect based in Dallas, Texas during the 20th century. His most notable contributions include the Art Deco structures of Fair Park while he oversaw planning and construction of the 1936 Texas Centennial Exposition. In 1970, in anticipation of imminent commercial growth brought on by the impending development of the Dallas/Fort Worth International Airport, he designed the First National Bank of Grapevine building at 1400 South Main Street. This iconic cubist structure served as a harbinger of the area's upcoming economic development.

George Dahl was born in Minneapolis to Norwegian immigrant parents, Olaf G. and Laura (Olson) Dahl. He received a B.Arch. from the University of Minnesota and a M.Arch. from Harvard University in 1923. He subsequently spent two years in Italy as a fellow at the American Academy in Rome.^[2]

In 1926, he began work for the Herbert M. Greene Co. in Dallas, Texas. He became a partner in Greene's firm in 1928, and the name of the firm was changed to Herbert M. Greene, LaRoche, and Dahl (later LaRoche and Dahl).

In 1943, Dahl founded his own firm, George Leighton Dahl, Architects and Engineers, Incorporated, with a nationwide practice. Dahl was also a pioneer in fast-track construction.^[3] Upon his retirement in 1973, he had produced some 3,000 projects throughout the country that are estimated to be worth $2 billion.

Dahl was married twice: in 1921 to Lillie E. Olson, with whom he had one daughter, and in 1978 to Joan Renfro. Dahl died of dehydration at the age of ninety-three at his home in Dallas.
