The House of Loredan-Santo Stefano was a cadet branch of the House of Loredan that existed from the 14th century until 1767. The branch was mainly settled in the Palazzo Loredan in Campo Santo Stefano, which they acquired in 1536 from the Mocenigo family. The progenitor of the branch is considered to be Gerolamo Loredan "dal Barbaro" di S. Vitale (d.~1474), father of Doge Leonardo Loredan and Dogaressa Caterina Loredan. Besides Leonardo, the branch also gave Doge Francesco Loredan.
