George Edwin Bergstrom (March 12, 1876 - June 17, 1955) was an American architect who designed The Pentagon in Arlington County, Virginia. He was born in Neenah, Wisconsin of Norwegian immigrant ancestry. He attended Phillips-Andover Academy, and was in the Yale University class of 1896. He earned a Bachelor of Science degree from Massachusetts Institute of Technology in 1899. Bergstrom settled in Los Angeles, California, in 1901. From 1905 to 1915, Bergstrom was in partnership with architect John Parkinson. The firm of Parkinson & Bergstrom designed numerous public and private buildings throughout Southern California, and designed many of the major office and commercial buildings erected in downtown Los Angeles during this period. Among these were the Los Angeles Athletic Club, the Alexandria Hotel, and the original building of Bullock's Department Store. The firm also received commissions for major projects as distant as Salt Lake City, first for the Kearns Building, erected in 1911 for U.S. Senator Thomas Kearns, a mining, newspaper, railroad and banking magnate and later, the Hotel Utah, now the Joseph Smith Memorial Building, was erected in 1909-1911.

After establishing his own practice in 1915, Bergstrom continued to design buildings throughout the region, including buildings for John C. Fremont High School, and Redlands High School, at Redlands, California. He designed buildings for the Elks Club and the Commercial Club in downtown Los Angeles, and collaborated with architect William Lee Woollett (1874-1955) on Grauman's Metropolitan Theatre (later called the Paramount Theatre) for impresario Sid Grauman. One of his most notable buildings of the period was the Pasadena Civic Auditorium in Pasadena, California, which he designed in association with architects Cyril Bennett and Fitch Haskell.

Between 1925 and 1931, Bergstrom associated on the Pasadena Civic Auditorium, with the Pasadena architectural firm of Haskell and Bennett, which was composed of John Cyril Bennett (1891-1957) and Fitch Harrison Haskell (1883-1962). The firm of Bergstrom and Witmer, Architects was in operation from 1941-1943. Bergstrom and David J. Witmer (1888-1973) acted as the Chief Architects for the Pentagon Building. Bergstrom and Witmer did the basic design work in a remarkably short time during 1941, between July 17 and July 22. Bergstrom was replaced as chief architect by Whitmer in April 1942 following Bergstorm's resignation due to unrelated charges of improper conduct while he was president of the American Institute of Architects.

Active in civic affairs, Bergstrom served as president of the Municipal Housing Commission for seven years and was a member of the Municipal Art Commission. He also served as chairman of the Advisory Board of the University of Southern California's School of Architecture. He was president of the Southern California chapter of the American Institute of Architects for two years, and served three years as director of the Institute. Active in numerous clubs and civic organizations, he served as a director of the Los Angeles Athletic Club, and was president of the Allied Architect's Association of Los Angeles.

He died in 1955 and was buried at Forest Lawn Memorial Park in Glendale, California.
