Henry Doubleday (1 July 1808 – 29 June 1875) was an English entomologist and ornithologist.

He and his brother Edward Doubleday spent their childhood collecting natural history specimens in Epping Forest.

He lived at the same time as his cousin Henry Doubleday (1810-1902) the scientist and horticulturist.

There is a blue plaque to him at the corner of High Street and Buttercross Lane, Epping.

He named a number of new species of moths, including the pigmy footman, Ashworth's rustic and marsh oblique-barred.
