The "Indian languages TRANSliteration" (ITRANS) is an ASCII transliteration scheme for Indic scripts, particularly for Devanagari script.

The need for a simple encoding scheme that used only keys available on an ordinary keyboard was felt in the early days of RMIM newsgroup where lyrics and trivia about Indian popular movie songs was being discussed. In parallel was a Sanskrit Mailing list that quickly felt the need of an exact and unambiguous encoding. ITRANS emerged on the newsgroup RMIM as early as 1994 (An early post from 1995 referring to ITRANS effort going on RMIM). ITRANS was spearheaded by Avinash Chopde and he developed a software early on as well. The latest version of the ITRANS software is version 5.30 released in July, 2001. ITRANS has been stabilized at this version.

ITRANS was in use for the encoding of Indian etexts - it is wider in scope than the Harvard-Kyoto scheme for Devanagari transliteration, with which it coincides largely, but not entirely. The early Sanskrit mailing list of early 1990s, almost same time as RMIM, developed into the full blown Sanskrit Documents project and uses ITRANS extensively, with thousands of encoded texts. With the wider implementation of Unicode, the traditional IAST is used increasingly also for electronic texts.
