Animesh Chakravorty (born 30 June 1935) is an Indian inorganic chemist.^[1][2]

Born in Mymensingh city (now in Bangladesh), Chakravorty had his school education there and later in Kolkata after the family moved there in 1948. He received his BSc degree from Scottish Church College, Kolkata (1955);^[3] MSc and PhD degrees (1957 and 1961) from College of Science, University of Calcutta, Kolkata.^[4] His doctoral work was directed by Sadhan Basu (1922-1992).^[5][6][7] He also worked independently.^[8] He then went to Cambridge, USA to work (1961-1964)  at  Massachusetts Institute of Technology  with Frank Albert Cotton (1930-2007) and later at Harvard University with Richard Hadley Holm (1933-2023). He returned home in 1964 and joined the Chemistry Faculty of Indian Institute of Technology, Kanpur (IITK)^[9] in as a lecturer, later becoming a professor (Head,1974–77). In 1977 he moved to Kolkata to lead the Department of Inorganic Chemistry at Indian Association for the Cultivation of Science (IACS), the oldest science research institute in India.^[10][11] He formally retired from IACS in 2000 but continued to work there till 2018 as an Emeritus Professor concurrently holding other externally supported  research positions.

Chakravorty's research concerns synthesis, structure and reactions of new transition metal complexes. He is best known for his work on  tuning of variable valence and scrutiny of associated redox phenomena.   He is an early pioneer in the systematic use of the now-common voltammetric techniques as a powerful research tool in variable valence transition metal coordination chemistry initially using a home-built equipment.^[12]  The  work of his group has resulted in nearly 300 original papers encompassing the chemistry of manganese,^{[13][14][15][16]} iron^{[17][18][19][20][21][22][23][24][25]} and nickel^[12][26][27] groups of elements and of  vanadium,^[28][29][30] molybdenum^[31] and copper.^[32] Representative examples are cited in each case. In the general framework of variable valence, the work is dotted with other themes such as ligand redistribution, spectroelectrochemical correlation, aromatic hydroxylation, oxygen atom transfer, cyclometalation, azo anion radical stabilization and more. The works on vanadium,^[28][29][30] manganese,^[13][14] iron^[22] and molybdenum^[31]  are of peripheral bioinorganic chemistry.^. Chakravorty is also the author of several major review articles and book chapters. Chakravorty has a secondary interest in history of chemistry. He published numerous articles on this issue and a book^[33] on the contributions of the greatest among early torch bearers of modern chemistry in India, Prafulla Chandra Rây (1861-1944).
