The Nagari Pracharini Sabha (Devanagari: नागरीप्रचारिणी सभा, Society for Promotion of Nagari), also known as Kashi Nagari Pracharini Sabha, was an organization founded in 1893 at the Queen's College, Varanasi for the promotion of the Devanagari script over the more common Kaithi script used for Hindi languages.

In 1899, it helped Chintamani Ghosh, proprietor of Indian Press, establish Saraswati, first monthly magazine in Modern Standard Hindi, which came out in January 1900.^[1] In 1929, Kala Parishad was transferred to Kashi Nagari Pracharini Sabha and given as new name Bharat Kala Bhavan (Indian Art Museum), which was formally opened on 3 March 1930.^[2]

Dictionaries are among the many scholarly publications by the Sabha. The Hiṅdi-śabdasāgara by Śyāmasundara Dāsa was first published 1916–1928, with a new edition published 1965–1975.
