Hyderabadi Muslims, also referred to as Hyderabadis, are a community of Deccani people, from the area that used to be the princely state of Hyderabad in the regions of Marathwada, Telangana, and Kalyana-Karnataka.

The Deccanis or Deccani people are an Indo-Aryan ethno-religious community of Deccani-speaking Muslims who inhabit or are from the Deccan region of Western and Southern India. The community traces its origins to the shifting of the Delhi Sultanate's capital from Delhi to Daulatabad in 1327 during the reign of Muhammad bin Tughluq. Further ancestry can also be traced from immigrant Muslims referred to as Afaqis, also known as Pardesis who came from Central Asia, Iraq and Iran and had settled in the Deccan region during the Bahmani Sultanate (1347). The migration of Muslim Hindavi-speaking people to the Deccan and intermarriage with the local Hindus whom converted to Islam, led to the creation of a new community of Hindustani-speaking Muslims, known as the Deccani, who would come to play an important role in the politics of the Deccan. Their language, Deccani, emerged as a language of linguistic prestige and culture during the Bahmani Sultanate, further evolving in the Deccan Sultanates.
