Muzaffar Shah I, born Zafar Khan, was the founder of the Muzaffarid dynasty in Medieval India, reigning over the Gujarat Sultanate from 1391 to 1403 and again from 1404 to 1411. The Kumbalgarh inscription says that Kshetra Singh defeated and captured Zafar Khan, King of Patan and the Khan remain in imprisonment with other Rajas.

The Gujarat Sultanate or Sultanate of Guzerat was a late medieval Indian kingdom in Western India, primarily in the present-day state of Gujarat. The kingdom was established in 1394 when Muzaffar Shah I, the Governor of Gujarat, declared independence from the Tughlaq dynasty of Delhi.
