Henry Tibbats Stainton (1822 – 1892) was an English entomologist. He was educated at King's College London. He was the author of Manual of British Butterflies and Moths and worked with the German entomologist Philipp Christoph Zeller, a Swiss, Heinrich Frey and another Englishman, John William Douglas The Natural History of the Tineina (1855–73).
Stainton was a very wealthy man and Mountsfield, his house in Lewisham, was one of London's more substantial residences set in its own park. Other wealthy entomologists often stayed at Mountsfield when visiting London, notably Alexander Henry Haliday and Deiterich Carl August Dohrn. Stainton was a member of both the Entomological Society of London and the Stettin Entomological Society. He encouraged interest in entomology among the wider public by holding weekly 'open evenings' at his house from 1856. Anyone over the age of 14 could freely visit Mountsfield on such evenings, perhaps to have a specimen identified, to view his collection or simply to learn more about entomology from Stainton himself, or other guests who may have been present.
Mountsfield, a substantial house and grounds, was built in 1845 for Stainton by his father as a wedding gift. The house and some 2.5 hectares (6 acres) of parkland lying to the south of it were bequeathed for a park by his widow in 1903, with the park opening to the public in August 1905.
