Thomas Vincent Campbell (23 June 1863-16 December 1930) was a physician, missionary and an entomological collector in India.

Thomas followed his brother in 1890 to work with the London Missionary Society at Jammalamadugu in Cuddapah district in India.

[2] Campbell married physician Florence Gertrude (born 1866, daughter of John William Longbottom and his second wife Elizabeth) of Halifax on 29 August 1891.

[3] Together they worked in India but exposure to patients led to him contracting tuberculosis and he returned to England to convalesce.

Treated by his wife, he recovered and they returned to India to establish the Ralph Wardlaw Thompson memorial hospital in Chikkaballapura.

He also proposed the establishment of sanatoria for the treatment of tuberculosis and this resulted in the founding of several including the Madanapalle TB sanatorium.

Campbell died suddenly of a stroke on the morning of 16 December 1930 just after he had finished packing off his insect specimens for the British Museum.
