Tamil Nadu Agricultural University (TNAU) is headquartered in Coimbatore, Tamil Nadu. It was established under the Tamil Nadu Agricultural University Act, 1971 (Tamil Nadu Act 8 of 1971), which received assent on 26 April 1971 and places the university’s seat within 25 kilometres of Coimbatore town limits.
The university’s telephone directory dated 30 September 2026 lists deans of 14 colleges and research institutes, at Coimbatore, Killikulam, Madurai, Mettupalayam, Periyakulam, Kudumiyanmalai, Kumulur, Tiruchirappalli, Eachangkottai and Thiruvannamalai, and nodal officers for four more at Karur, Chettinad, Keelvelur and Paiyur. It also lists research directorates and the Tamil Nadu Rice Research Institute at Aduthurai. The same directory names no Vice-Chancellor; a university press note of 7 January 2026 said the Registrar in charge would perform the Vice-Chancellor’s duties.
