American colonial architecture includes several building design styles associated with the colonial period of the United States, including First Period English (late-medieval), Spanish Colonial, French Colonial, Dutch Colonial, and Georgian. These styles are associated with the houses, churches and government buildings of the period from about 1600 through the 19th century.

French colonial architecture includes several styles of architecture used by the French during colonization. Many former French colonies, especially those in Southeast Asia, have previously been reluctant to promote their colonial architecture as an asset for tourism; however, in recent times, the new generation of local authorities has somewhat "embraced" the architecture and has begun to advertise it. French Colonial architecture has a long history, beginning in North America in 1604 and being most active in the Western Hemisphere until the 19th century, when the French turned their attention more to Africa, Asia, and the Pacific.
