Sir Richard Southey KCMG (25 April 1808 – 22 July 1901) was a British colonial administrator, cabinet minister and landowner in South Africa.
Southey was the son of 1820 Settlers leader George Southey of , Devon, and later of Bloemhof Farm, Albany. He voyaged to South Africa with his family aboard the Kennersley Castle in 1820. The family were the cadet branch of a family of Devonshire gentry and were cousins to Poet Laureate Robert Southey.
Southey began his career as an officer during the Frontier Wars of the Eastern Cape. He was a lieutenant in the Albany Mounted Sharpshooters and Captain of the Corps of Guides.
It was during this conflict, in May 1835, that the Xhosa paramount chief Hintsa was shot in the head by Richard Southey’s brother, George. Hintsa had been taken captive by Governor Harry Smith, during peace talks, and was being guarded by Southey's Corps of Guides when he was killed while trying to escape. He was shot in the back of the head by George Southey after asking for mercy. His body was partially dismembered for trophies afterwards, by two of the Southey brothers – George and William – among others.
Richard Southey worked particularly closely with Sir Harry Smith during this time, and later became his Secretary in Natal. He went on to fill two of the highest offices in the colonial government; firstly as Treasurer (1861–1864) and later as Colonial Secretary (1864–1872), replacing his moderate colleague Rawson W. Rawson.
As Colonial Secretary, he consistently and strongly opposed the growing movement for "Responsible Government" (local democracy) in the Cape, that was led by his fiercest political enemy, John Molteno. He was also noted for his expansionist politics regarding the Cape's neighbouring states. He firmly believed in bringing all southern African states – especially the remaining indigenous African states – under British imperial rule. This strategy, together with his "native policy" was heavily criticised by the local Cape Parliament of the time, which was dominated by liberal politicians such as Saul Solomon.
