Kishori Mohan Bandyopadhyay (Bengali: কিশোরীমোহন বন্দ্যোপাধ্যায় ) (1877 - 1929) was an Indian scientist, social worker and freedom fighter. He worked as one of the laboratory assistants to Ronald Ross in 1898 at the Culcutta Presidency General Hospital. After Ross was awarded the Nobel Prize in Physiology or Medicine in 1902 for the discovery of trasnmission of malaria by mosquito, Bandyopadhyay was awarded King Edward VII's Gold Medal in 1903 for his contribution.
The Bandyopadhyay family was originally from Jessore, now in Bangladesh. The family moved to Panihati, 24 Paragana, West Bengal. Bandyopadhyay was born in Entally area of Kolkata at his maternal grand parents' home. His father Nanilal was a teacher in Sanskrit and Persian literature and languages. His two elder brothers Lalmohan and Haridas were teachers in Bengali and Sanskrit. The family house was called Nilambati. Now part of the house is demolished but the original plaque is still preserved. Bandyopadhyay was educated at Panihati vernacular school. Then he was sent to his maternal grand father's house at Kolkata where he completed Entrance Examination of University of Calcutta and graduated in science from Presidency College.
In February 1898 Ronald Ross was searching for an able assistant, and Bandyopadhyay was able to impress Ross and was recruited.

With his magic lantern he made public slide shows to educate villagers about malaria and anopheles mosquito. He joined politics and later campaigned for Bidhan Chandra Roy who contested against Surendranath Banerjee and won.
