Giorgio Ordelaffi (died 1423) was lord of Forlì and Papal vicar in Romagna (northern Italy).
She was a daughter of Ludovico Alidosi, Lord of Imola.
Ordelaffi kept the seigniory of Forlì from 1411 until his death, moving his residence in the current Palazzo Comunale.
Just before his death, when his son Teobaldo II Ordelaffi was still young, he offered to Filippo Maria Visconti of Milan the occasion to invade Romagna in 1423, initiating the 30-year long Wars in Lombardy.
