The Honour of Richmond was a feudal barony in what is now mainly North Yorkshire, England. The honour was two tiers below Yorkshire, the middle tier being the North Riding.

Alan Rufus, alternatively Alanus Rufus (Latin), Alan ar Rouz (Breton), Alain le Roux (French) or Alan the Red, 1st Lord of Richmond, was a Breton nobleman, kinsman and companion of William the Conqueror during the Norman Conquest of England. He was the second son of Eozen Penteur by Orguen Kernev. William the Conqueror granted Alan Rufus a significant English fief, later known as the Honour of Richmond, in about 1071.
