Obizzo III d'Este (14 July 1294 – 20 March 1352) was the marquess of Ferrara from 1317 until his death.
He was the son of Aldobrandino II d'Este and Alda Rangoni.
Aldobrandino was lord of Ferrara together with his brother Rinaldo and Niccolò, and his cousin Folco II, but in the end reigned as sole ruler. He managed to enlarge the family possessions with the conquests of Modena (1336) and Parma (1344–1346).
He married first in 1317 Jacopa Pepoli and then in 1347 Lippa Ariosti. Obizzo died in 1352, being succeeded by his son Aldobrandino.

The younger branch of the House of Este included rulers of Ferrara (1240–1597), and Modena and Reggio (1288–1796).
Edward Gibbon said the family originated from the Roman Attii family, which migrated from Rome to Este to defend Italy against the Ostrogoths.

Oberto's grandson, Albert Azzo II, Margrave of Milan (996–1097) built a castle at Este, near Padua, and named himself after it. He had three sons from two marriages, two of whom became the ancestors of the two branches of the family:
