Kutchi (also spelt Cutchi, Kutchhi or Kachchhi; Gujarati: કચ્છી, Sindhi: ڪڇي, Hindi: कच्छी , Urdu: کچھی) is an Indo-Aryan Language spoken in the Kutch region of the Indian state of Gujarat as well as in the Pakistani province of Sindh.

Kachhi is related to Sindhi, spoken in neighboring Sindh, Pakistan and parts of India, and Gujarati, because the Kutch District is geographically between Sindh and Gujarat.

Kachhi is often thought to be a mixture of Sindhi, Gujarati and Rajasthani. Its lexical content shows the very large extent to which the language is a complex combination of Sindhi and Gujarati. It is likely that such linguistic similarities are the result of migrations over the centuries across the desert stretching from present-day Sindh to Saurashtra and Kutchh to the east, and Rajasthan.

Most Kachhis living in India are bilingual or trilingual, due to exposure to closely related neighbouring languages such as Gujarati. Many Pakistanis are also bilingual or trilingual; many residents of Karachi speak Kutchi. Kutchi can not be written in Urdu script but it can be written in Sindhi or Gujarati scripts.
