Roberto Alidosi
Roberto Alidosi (died 29 November 1362) was an Italian nobleman who ruled Imola as papal vicar from 1350, succeeding his father Lippo II Alidosi. In 1356 he served as captain of the papal army.
He married first Michelina Malatesta, daughter of Malatesta III Malatesta of Pesaro, and after her death Giacoma Pepoli. On his death at Imola in 1362 he was succeeded by his son Azzo; a second son, Bertrando, later held the signoria as well.
