José Christiano de Freitas Henriques Junior (1832–1902), mostly known as Christiano Junior, was a Portuguese-born photographer. He was one of the most prominent photographers in Argentina in the 19th century. During a time, Christiano Junior was associated with British colleague Alexander Witcomb, who would later acquire Junior's studio and photographs, adding them to his own material. In 1970, Witcomb's entire artwork became part of the General Archive of the Nation as an evidence of the history of Argentina registered on photographs.
