Germaine Luise Krull (20 November 1897 – 31 July 1985) was a photographer, political activist, and hotel owner. Her nationality has been categorized as German, French, and Dutch, but she spent years in Brazil, Republic of the Congo, Thailand, and India. Described as "an especially outspoken example" of a group of early 20th-century female photographers who "could lead lives free from convention", she is best known for photographically illustrated books such as her 1928 portfolio Métal.
