Indira Nath (born 14 January 1938) is an Indian immunologist. Her major contribution in medical science deals with mechanisms underlying immune unresponsiveness in man, reactions and nerve damage in leprosy and a search for markers for viability of the Leprosy bacillus. Prof. Nath's fields of specialisations are Immunology, Pathology, Medical biotechnology and communicable diseases. 
Nath received her MBBS from All India Institute of Medical Sciences (AIIMS), New Delhi. She joined AIIMS as MD (pathology) after mandatory hospital training in the UK. During the 1970s, India has the world's largest number of leprosy patients in the world of 4.5 million.
In 1970 Nath was in the UK with a Nuffield Fellowship. During this period she came to specialize in immunology. She worked in the area of infectious diseases, particularly leprosy, with Professor John Turk at the Royal College of Surgeons and Dr RJW Rees at the National Institute for Medical Research, London.
After coming back to India, she joined Professor GP Talwar's Department of Biochemistry at AIIMS, which had just initiated immunology research in India. Later in 1980 she moved to the Department of Pathology and she founded and established Department Biotechnology (1986) at AIIMS. She retired in 1998 but continued to work at AIIMS as INSA-SN Bose Research Professor.
She received DSc from Pierre and Marie Curie University, Paris in the 2002. She was invited for the post of Dean of School of Medicine in Asian Institute of Medicine, Engineering and Technology in Malaysia and also as Director of Blue Peter Research Centre (Lepra Research Centre), Hyderabad.
Her research is focused on the cellular immune responses in human leprosy. She has over 120 publications, invited reviews, opinion/comments on recent developments in international journals. Her discovery and her pioneering work are a significant step towards the development of treatment and vaccines for leprosy.
