Ernest G. Southey (January 23, 1874 - November 20, 1945)^[1] was an American architect from Bridgeport, Connecticut.

Having begun his practice by 1902, and continuing until his 1945 death, Ernest G. Southey had a career spanning almost the entire first half of the twentieth century. During that period, he designed a number of major residences, commercial buildings, and the Bassick High School. He was a member of the American Institute of Architects from 1916, and was cited for his architectural achievement during Bridgeport's centennial celebration in the 1930s.^[2]

Southey's son, David Ludgate Southey (1911-1974), was also an architect.^[3]

At least one of his designs has been placed on the National Register of Historic Places, and several others are contributing properties in historic districts.^{[citation needed]}
