Cirupitty Wyravanathar Thamotharampillai (Pillai) (Tamil: சி. வை. தாமோதரம்பிள்ளை; 12 September 1832 – 1 January 1901)), sometimes referred to by the initials as C. Y., devoted his energies to the work of editing and publishing some of the oldest works of classical Tamil poetry and grammar. According to Kamil Zvelebil, he was the first person to be "engaged in the rediscovery of the earliest classical literature" of Tamil, and that his "greatness and merits have never been acknowledged".
