The Bibi Ka Maqbara (English: "Tomb of the Lady") is a tomb located in the city of Aurangabad in the Indian state of Maharashtra. It was commissioned in 1660 by the Mughal emperor Aurangzeb's son, Prince Azam Shah, in the memory of his mother Dilras Banu Begum (posthumously known as Rabia-ul-Durrani). It bears a striking resemblance to the Taj Mahal, the mausoleum of Aurangzeb's mother, Mumtaz Mahal, which is why it is also called the Taj of the Deccan. Bibi Ka Maqbara is the second largest structure built by Aurangzeb, the largest being the Badshahi Mosque.

The comparison to the Taj Mahal has often obscured its very own considerable charm. Bibi Ka Maqbara is the "principal monument" of Aurangabad and its historic city. An inscription found on the main entrance door mentions that this mausoleum was designed and erected by Ata-ullah, an architect and Hanspat Rai, an engineer respectively. Ata-ullah was the son of Ustad Ahmad Lahauri, the principal designer of the Taj Mahal. Aurangzeb's son, Muhammad Azam Shah was in later years put in charge of overseeing the repair-work of the mausoleum by Shah Jahan.
