Caroline of Brunswick (17 May 1768 – 7 August 1821) was the wife of King George IV. Her parents were Charles William Ferdinand, Duke of Brunswick and Princess Augusta of Great Britain.
Caroline married George on 8 April 1795, when he was the Prince of Wales. That made Caroline the Princess of Wales. When George became king on 29 January 1820, Caroline became Queen Consort of the United Kingdom. Caroline and George had one child, Princess Charlotte of Wales. They separated in 1796.
Caroline died on 7 August 1821 at the age of 53. Her physicians thought she had an intestinal obstruction, but she may have had cancer. There were also rumours at the time that she had been poisoned.
