Padshah Begum was a superlative imperial title conferred upon the empress consort or 'First Lady' of the Mughal Empire and was considered to be the most important title in the Mughal harem or zenana. This title can be equivalent with "empress" in English, but in only approximate terms in the Mughal context.

Padishah, sometimes romanised as padeshah, patshah, padshah or badshah, is a superlative sovereign title of Persian origin.
