Laird () is the owner of a large, long-established Scottish estate. In the traditional Scottish order of precedence, a laird ranked below a baron and above a gentleman. This rank was held only by those lairds holding official recognition in a territorial designation by the Lord Lyon King of Arms. They are usually styled [name] [surname] of [lairdship]. However, since "laird" is a courtesy title, it has no formal status in law.

Historically, the term bonnet laird was applied to rural, petty landowners, as they wore a bonnet like the non-landowning classes. Bonnet lairds filled a position in society below lairds and above husbandmen (farmers), similar to the yeomen of England.

An Internet fad is the selling of tiny souvenir plots of Scottish land and a claim of a "laird" title to go along with it, but the Lord Lyon has decreed these meaningless for several reasons.
