Formerly known as the Oriental Library, the Oriental Research Institute at Mysore, India, is a research institute which collects, exhibits, edits, and publishes rare manuscripts written in various scripts like Devanagari (Sanskrit), Brahmic (Kannada), Nandinagari (Sanskrit), Grantha, Malayalam, Tigalari, etc.
The Oriental Library was started in 1891 under the patronage of Maharaja Chamarajendra Wadiyar X. It is located at the northern end of Krishnaraja Boulevard (adjacently opposite to Mysore University's Crawford Hall), in the architecturally attractive Jubilee Hall built in 1887 to commemorate the golden jubilee of Queen Victoria's accession to the British throne. It was a part of the Department of Education until 1916, in which year it became part of the newly established University of Mysore. The Oriental Library was renamed as the Oriental Research Institute in 1943.
