Hyderabadi Urdu (Urdu: حیدرآبادی اردو) is a variety of Dakhini Urdu, spoken in areas of the former Hyderabad State, corresponding to the Indian state of Telangana, the Marathwada region of Maharashtra and the Kalyana-Karnataka region of Karnataka.

It is natively spoken by the Hyderabadi Muslims and their diaspora. It contains loan words from Indian languages like Marathi, Telugu, Kannada and foreign languages like Arabic, Turkic and Persian. Hyderabadi is considered to be a northern variety of Dakhini.

Hyderabadi is mutually intelligible with most Hindi/Urdu speakers but has distinctive features from interaction with local Indian Languages such as Marathi, Telugu, and Kannada.

The letter ق (qāf) is pronounced as an unvoiced velar fricative /x/ with the same pronunciation as خ (khe) whereas in Standard Hindustani dialects the ق is pronounced as a velar plosive /k/ with the same pronunciation as ک (kāf), or in more educated settings as /q/. For example, the word 'qabar' (grave) is pronounced almost identical as 'khabar' (news).

Distinct vocabulary unique to Hyderabadis:

The suffix "ān" is often used to mark plurality. The letter 'n' is an almost silent nasal stop. For example, Log لوگ (people) would become Logān لوگاں, Bāt بات (talk) would become Bātān باتاں, Ādmi آدمی (men) pronounced as Admi ادمی would become Admiyān ادمیاں, etc. in the Hyderabadi dialect.

While talking, many long a's (as in "father") are pronounced "uh" as in "hut." For example, instead of "ādmi" آدمی (man) or "rāsta" راستہ (path) in Orthodox Urdu, Hyderabadi would use "admi" ادمی and "rasta" رستہ. Similarly "bhūl" بھول (to forget), "ṭūṭ" ٹوٹ (to break) and "čūṛi'ān" چوڑیاں (bangles) is "bhul" بُھل, "ṭuṭ" ٹُٹ and "čuṛiyān" چُڑیاں in Hyderabadi.

In the early sixties, film star Mehmood popularized another dialect in Indian films, Dakhni slang, which originates from former Mysore State.
