Sir Cattamanchi Ramalinga Reddy (10 December 1880 – 24 February 1951), also popularly known as Sir C. R. Reddy, was an educationist and political thinker, essayist and economist, poet and literary critic. He was a prominent member of the Justice Party and an ardent champion of the non-Brahmin movement, joining the movement to unite the non-Brahmin communities. He wrote his works in Telugu and English; these reveal his deep love for Indian classics and his learning in these texts, as well as the modernity of his outlook.

Reddy was the educationalist who played a major role in shaping the educational policy in India. He was also the recipient of a British Knighthood in honour of his service to the country. He was the founder of Andhra University and also served as its first Vice-Chancellor from 1926 to 1931 and in a further second term from 1936 to 1949.
