The Principal Clerk of Session and Justiciary is the clerk of court responsible for the administration of the Supreme Courts of Scotland and their associated staff. The Keeper of the Signet grants a commission to the Principal Clerk of Session to allow His Majesty's Signet to be used.

Gillian Prentice was the first woman to hold the post. The Principal Clerk is Yvonne Taylor.

The modern office unites the originally separate offices of Principal Clerk of Session (of the Court of Session) and Principal Clerk of Justiciary (of the High Court of Justiciary).
