Kaithi, also called Kayathi or Kayasthi, is a historical Brahmic script that was used widely in parts of Northern and Eastern India, primarily in the present-day states of Uttar Pradesh, Jharkhand and Bihar. In particular, it was used for writing legal, administrative and private records. It was used for a variety of Indo-Aryan languages, including Angika, Awadhi, Bhojpuri, Hindustani, Magahi, and Nagpuri.

The Brahmic scripts, also known as Indic scripts, are a family of abugida writing systems. They are used throughout the Indian subcontinent, Southeast Asia and parts of East Asia. They are descended from the Brahmi script of ancient India and are used by various languages in several language families in South, East and Southeast Asia: Indo-Aryan, Dravidian, Tibeto-Burman, Mongolic, Austroasiatic, Austronesian, and Tai. They were also the source of the dictionary order (gojūon) of Japanese kana.
