The Halmidi inscription is the oldest known Kannada language inscription in the Kadamba script. While estimates vary slightly, the inscription is often dated to between 450 CE - 500 CE. The inscription was discovered in 1936 by Dr. M. H. Krishna, the Director of Archaeology of the (princely) State of Mysore (present-day Karnataka region of India), in Halmidi, a village in the Hassan district. The original inscription is kept in the Office of the Director of Archaeology and Museums, Govt. of Karnataka, Mysore, and a fibreglass replica has been installed in Halmidi.
