The Right Honourable the Lord Lyon King of Arms, the head of Lyon Court, is the most junior of the Great Officers of State in Scotland and is the Scottish official with responsibility for regulating heraldry in that country, issuing new grants of arms, and serving as the judge of the Court of the Lord Lyon, the oldest heraldic court in the world that is still in daily operation.

The historic title of the post was the High Sennachie, and he was given the title of Lord Lyon from the lion in the coat of arms of Scotland.

The post was in the early nineteenth century held by an important nobleman, the Earl of Kinnoull, whose functions were in practice carried out by the Lyon-Depute. The practice of appointing Lyon-Deputes, however, ceased in 1866.

The Lord Lyon is responsible for overseeing state ceremonial in Scotland, for the granting of new arms to persons or organisations, and for confirming proven pedigrees and claims to existing arms. He also registers and records new clan tartans, upon request from the clan chief. The Lyon Register (officially the Public Register of All Arms and Bearings in Scotland), on which the Lord Lyon records all Scotland's coats of arms, dates from 1672.

As Lyon Court is a government department, fees paid for granting coats of arms are paid to the Treasury. The misuse of arms is a criminal offence in Scotland, and treated as tax evasion. Prosecutions are brought before Lyon Court, Lord Lyon being the sole judge. Appeals from the Lyon Court can be made to the Court of Session in Edinburgh. There is no appeal if the Lord Lyon refuses to grant a coat of arms, as this is not a judicial function, but an exercise of his ministerial function, although an appeal by way of judicial review may succeed if it can be shown that the Lord Lyon acted unreasonably.

The Lord Lyon has several English equivalents:

The Lord Lyon is also one of the few individuals in Scotland officially permitted to fly the "Lion Rampant", the Royal Banner of Scotland.
