The Injuids (also Injus or House of Inju) were an Iranian[1] dynasty of Persian origin that came to rule over the cities of Shiraz and Isfahan during the 14th century.

The Ilkhan had given Sharaf al-Din Mahmud Shah control of the injü (or inji; the Mongol word for the royal estates).

His power displeased Öljeitü's successor Abu Sa'id, who ordered Sharaf al-Din removed and sent a Sheikh Hussein ibn Juban to replace him.

Mas'ud Shah then served as vizier under the Jalayirid puppet Ilkhan Muhammed Khan; when the latter was killed, he made his way to Shiraz.

Mas'ud Shah attempted to take advantage of Chobanid infighting, and allied with Yagi Basti to take the city, which had in the meantime fallen into the hands of Abu Ishaq.

When Yagi Basti murdered Mas'ud Shah that same year, Abu Ishaq became the sole surviving son of Sharaf al-Din.

The chief of another quarter, fearing for his people, gave the key for his gate to Mubariz al-Din's son Shah Shuja.
