Major-General Thomas Hardwicke (1756 – 3 March 1835) was an English soldier and naturalist. He was in India from 1777 to 1823. He collected many specimens of natural history and had them painted by Indian artists. From these paintings many new species were described. Several of these species are named after him. On returning to England he collaborated with the zoologist John Edward Gray to publish "Illustrations of Indian Zoology" (1830–1835).
