Nathaniel Hone the Younger was an Irish painter, the great-grand-nephew of the painter Nathaniel Hone.

Hone studied at Trinity College Dublin. He began his career as a railway engineer but gave this up to study art in Paris. Most of his later paintings are landscapes, very often enlivened with animals and occasionally with figures. He was a member of the Hone family. In France he was influenced by the painter Gustave Courbet who was taking a new and quite revolutionary realistic approach. His closest painting tips were, however, from another French impressionist, Camille Corot. Hone became a close friend of one of Corot's followers at the Barbizon School of landscape painting. At Barbizon he learned to appreciate colour, texture and tone in the landscape, and applied it in strong and confident brushworks to the painting of Irish subjects on his return. In Paris, Hone worked closely with artist Édouard Brandon, also a follower of Corot's, and stayed with him at 44, rue du Notre Dame de Lorette.

Hone established Malahide Golf Club in 1892 and is now one of Dublin's premier golf courses and restaurants.
