Katie Swan (born 24 March 1999 in Bristol) is a British tennis player.
Swan was born in Bristol, to parents Nicki and Richard. Whilst on holiday in Portugal when she was seven, she took tennis lessons. Her teacher had once played for Portugal and told her parents that she showed real talent and could represent her country in the future. On the family's return to Abbots Leigh, Bristol, Swan had regular tennis lessons with Rob Hawkins, junior programme manager and head coach at the David Lloyd club. Hawkins coached Swan until she was 11, watching her develop into a promising player on the international circuit.
Swan was head girl at Bristol prep The Downs School and a keen hockey player, representing Avon and her school when they qualified for the Under-13 national finals. She briefly attended the independent Bristol Grammar School until the family moved to Wichita, Kansas, United States, in 2013 due to her father's job in the oil industry. Swan was one of the very few junior players on the competitive circuit who continued in school, Wichita Collegiate School, though from August 2015 she took online classes.
