M. S. Krishnan (1896-1961) was an Indian geologist, renowned for his contributions to the geological mapping and mineral resource assessment of India, particularly during the pre-independence and early post-independence periods. He played a pivotal role in establishing and developing geological institutions in India.

Krishnan obtained his D.I.C. (Diploma of Imperial College) and Ph.D. from the Royal College of Science, London. He served as a geologist with the Geological Survey of India (GSI) for many years, eventually rising to the position of Director. His work at the GSI involved extensive fieldwork, covering diverse geological terrains across the Indian subcontinent.

He conducted significant work on the Gondwana formations and the mineral resources of various regions, including peninsular India. He authored several important publications, including "Geology of India and Burma," which became a standard textbook for geology students in India for decades.

After retiring from the GSI, Krishnan served as the Director of the Indian Bureau of Mines. He also held positions at various universities and scientific organizations, contributing significantly to geological education and research in India. He was a Fellow of the Indian National Science Academy and received numerous awards and honors for his contributions to the field of geology. His work laid a strong foundation for the development of geological sciences in India and continues to be relevant for understanding the country's geological history and mineral wealth.
