General Sir John Fraser, GCH (1760 – 14 November 1843) was a British Army officer.
On 1 January 1800 he was appointed colonel of the Royal African Corps, composed of military offenders from various regiments pardoned on condition of life-service in Africa and the West Indies.
With this corps, he served on the west coast of Africa in 1801–1804, and made a brave but unsuccessful defence of Gorée in Senegal, against a superior French force from Cayenne.
Gorée was compelled to surrender on 18 January 1804, but not before the enemy's loss exceeded the total strength of the defenders at the outset.
[2] He was made Lieutenant-Governor of Chester Castle in 1828, GCH in 1832, and was a member of the consolidated board of general officers.
