Crown advocate is a title used in Britain and some former British colonies for a government prosecutor. In former British Colonies and certain British extraterritorial courts the title is (or was) used by the senior government advocate.

In the United Kingdom, there are three levels of crown advocate as well as senior and principal crown advocates employed by the Crown Prosecution Service (CPS).

Level One crown advocates conduct conduct the prosecution of non-jury work, usually in the Magistrates' Court. As well as all non-jury work, level 2 crown advocates conduct jury trials in the Crown Court, ranging from straightforward, very short trials to those of medium length and complexity towards the top end of level 2. Level Three crown advocates conduct jury trials in the more serious and complex cases. Senior crown advocates conduct jury trials in very serious, sensitive and complex cases, including rape, substantial historic child abuse, homicide cases and cases involving issues of national security. Principal crown advocates conduct advocacy in the CPS' complex cases across areas and casework divisions and perform at a standard expected of a King's Counsel.^[1]

The position of Crown Advocate was created in the British Supreme Court for China and Japan in 1878 and existed until 1943 when the court was abolished. The first holder of the position was Nicholas John Hannen. The position was similar to the position of an Attorney General in a colony. The Crown Advocate was not a full-time employee of the Foreign Office but received payment for acting as Crown Advocate. The Crown Advocate was allowed to accept cases from private clients that did not conflict with his role as Crown Advocate.^[2]

The position of Crown Advocate was created in 1839 to replace the office of Attorney General. The position was abolished in 1922 and taken over by the Treasury Counsel. In 1936, the role of Treasury Counsel was taken over by the newly re-created office of Attorney General.^[3]
