John Porter Clark (1905–1991) was an American architect. He worked with Albert Frey on several projects in Palm Springs, California, and was part of the firm. He has been referred to as a "mid-century modernist", and credited as one of the pioneers of "Desert Modernism", by using local rock, concrete blocks, metal and glass. His own house, the John Porter Clark House (1939) in Palm Springs, has been described as being in the international style and as one of the earliest examples of residential modern architecture in Southern California.
