Kokborok Day is observed in Tripura, India, every January 19. This annual celebration honors the Kokborok language, which is spoken by the indigenous Borok people, also known as the Tripuri people. The day commemorates the recognition of Kokborok as an official language of Tripura in 1949, alongside Bengali, after it had been the sole official language for three decades. The celebration includes cultural programs and activities organized by the state government. Kokborok serves as an umbrella term for various dialects, with Debbarma recognized as the standard for literature and education. Despite being the mother tongue of the majority in Tripura, Kokborok is classified as a vulnerable language, with approximately 695,000 speakers as per the 2001 census.
