Sinibaldo II Ordelaffi (1467â 14 July 1480 Forlì) was the lord of Forlì in 1480, inheriting it from his father Pino III Ordelaffi. After his death the Ordelaffi lost the control of the city, who was acquired by Pope Sixtus IV's nephew Girolamo Riario. Sinibaldo's relative Francesco V Ordelaffi shortly claimed the lordship, but in vain.
