Merritt H. Starkweather (1891–1972) was a Tucson, Arizona, architect and civic leader.

A native of Oshkosh, Wisconsin, after visiting the 1915 Panama–California Exposition, he moved to Tucson and began working in an elegantly simplified Spanish Colonial Revival Style architecture.

Several of his works are listed for their architecture on the National Register of Historic Places.

Starkweather buildings reflect a sophisticated understanding of the Art Deco movement – both the Starweather Home on Adams Street and in El Encanto Estates are examples of Pueblo Deco Style.

In 1937, he founded the Arizona chapter of the American Institute of Architects and in 1968 was named an AIA Fellow.
