Rosalind Edith Rajagopal (née Williams; June 20, 1903 – January 24, 1996) was a long-time director of the Happy Valley School (Besant Hill School) in Ojai, California. She co-founded the school in 1946 with Indian philosopher Jiddu Krishnamurti, Italian literary critic Guido Ferrando, and English author Aldous Huxley.

Through her family's involvement in the Theosophical Society she became acquainted with Jiddu Krishnamurti and his ailing younger brother Nitya in 1922. Rosalind developed close ties with the brothers, and sometime after her 1927 marriage to their fellow Indian associate D. Rajagopal, she and Krishnamurti began a long-term romantic relationship. This became a source of controversy when it was publicly revealed in the 1991 book Lives in the Shadow with J. Krishnamurti, written by her daughter, Radha Rajagopal Sloss.
