Old Dhaka is a term used to refer to the historic old city of Dhaka, the capital of Bangladesh. It was founded in 1608 as Jahangirabad or Jahangirnagar, the capital of Mughal Province of Bengal and named after the Mughal emperor Jahangir. It is located on the banks of the Buriganga River. It was one of the largest and most prosperous cities of the subcontinent and the center of the worldwide muslin trade. The then Nawab of Bengal Murshid Quli Khan shifted the capital from Dhaka to Murshidabad in the early-18th century. With the rise of Calcutta during the British rule, Dhaka began to decline and came to be known as the "City of Magnificent Ruins". The British however began to develop the modern city from the mid-19th century.

The Old Dhakaites are an Indo-Aryan cultural group viewed as the original inhabitants of Dhaka. They are sometimes referred to as simply Dhakaites or Dhakaiya. Their history dates back to the Mughal period with the migration of Bengali cultivators and merchants to the city. The cultivators came to be known as Kutti and they speak Dhakaiya Kutti, a dialect of Bengali and the merchants came to be known as Khoshbas and speak Dhakaiya Urdu. There are sizeable populations in other parts of Bangladesh. The Old Dhakaiyas maintain a distinct regional identity in addition to their ethnic Bengali identity, due to cultural, geographical and historical reasons. They have been described as a wealthy but very closed-off community; evidently being a minority in their own hometown. It is said that some people living in Greater Dhaka are even unaware of the existence of an Urdu-speaking non-Bihari minority community although their presence dates back centuries.
