Scotland differs from the rest of the United Kingdom in that the lowest rank of its peerage is not the Baron. In Scotland, the term "baron" refers to a feudal baron. Therefore, the Scottish equivalent to the English baron is the Lord of Parliament.

A male holder of a Lordship is designated a "Lord of Parliament," while there is no similar designation for female holders. Lords of Parliament are referred to as Lord X, while female holders of Lordships of Parliament are known as Lady X. The wife of a Lord of Parliament is also Lady X. Children of Lords of Parliament and female holders of Lordships of Parliament are styled The Honourable [Forename] [Surname]. After the death of the father or mother, the child may continue to use the style.
