The Honour of Richmond (or Richmondshire) was a feudal barony in what is now mainly North Yorkshire, England.

The honour was granted to Count Alan Rufus (also known as Alain le Roux) by King William the Conqueror (as a gift of thanks for his services in the Conquest) sometime from after the Domesday Book of 1068 to just after the earl's death in 1071, the date is uncertain.

[3] The manor of Gilling was the caput of the barony until Count Alan moved it to Richmond Castle.

[4] The Honour of Richmond, being 60 km (37 mi) from east to west and 45 km (28 mi) from north to south, comprised most of the land between the River Tees and the River Ure and ranged in its landscape from the bleak mountainous areas of the Pennines to the fertile lowlands of the Vale of York.

The eastern border followed small streams and minor landmarks from the previous watershed to the Swale.
