The Dakshina Bharat Hindi Prachar Sabha Act, 1964 is a significant piece of legislation enacted by the Indian Parliament to declare the Dakshina Bharat Hindi Prachar Sabha (DBHPS) as an institution of national importance. This Act recognizes the Sabha's pivotal role in promoting the Hindi language and its teaching in South India, reflecting the post-independence emphasis on linguistic unity and national integration.

The Dakshina Bharat Hindi Prachar Sabha was established in 1918 by Mahatma Gandhi as part of the broader Indian independence movement. Gandhi envisioned Hindi as a unifying language for India, bridging the linguistic divide between the Hindi-speaking North and the Dravidian-language-speaking South. The Sabha's mission was to propagate Hindi in southern states, fostering national cohesion and cultural exchange. Over time, its efforts gained recognition, leading to its formal institutionalization under this Act in 1964.
