John S. Johnston (c.1839 – December 17, 1899) was a late 19th-century maritime and landscape photographer. He is known for his photographs of racing yachts and New York City landmarks and cityscapes.
Very little is known about his life. He was evidently born in Britain in the late 1830s, and was active in the New York City area in the late 1880s and 1890s. He died in 1899.
