Rizzardo IV da Camino (1274 – April 12, 1312) was an Italian nobleman and military leader, a member of the da Camino family and lord of Treviso. He was the son of Gherardo III da Camino, first lord of Treviso from the family, and Alice da Vivaro. In 1295 he was created knight in Rovigo by marquis Azzo VIII d'Este and was married to Catherine of Ortenburg, a family with whom his father wanted to create commercial ties. In the 1280s he was frequently sent by his father in diplomatic missions to Friuli and, in 1301, Rizzardo shared with his father the lordship of Treviso, succeeding him after his death in 1306.
