Lord of the manor is a title that, in Anglo-Saxon England and Norman England, referred to the landholder of a rural estate. The titles date to the English feudal system. The lord enjoyed manorial rights as well as seignory, the right to grant or draw benefit from the estate. The title continues in modern England and Wales as a legally recognised form of property that can be held independently of its historical rights. It may belong entirely to one person or be a moiety shared with other people. The title is known as Breyr in Welsh.

Lord is an appellation for a person or deity who has authority, control, or power over others, acting as a master, chief, or ruler. The appellation can also denote certain persons who hold a title of the peerage in the United Kingdom, or are entitled to courtesy titles. The collective "Lords" can refer to a group or body of peers.
