Tiffany Porter

Tiffany Adaeze Porter (née Ofili; born 13 November 1987) is a track and field athlete with joint British and American nationality who specialises in the 100 metres hurdles. She represented the United States as a junior, but began representing Great Britain in 2010 on joining the senior ranks after moving to England and competed for Great Britain at the 2012 Olympic Games in London.

Porter won a bronze medal in the 100 m hurdles at the 2013 World Championships. In 2014, she won a silver medal representing England at the Commonwealth Games. Later in 2014 she took her first major title, a gold medal at the European Championships, becoming the first British woman to win a European title in the event. Her personal best of 12.51 set in 2014 was the British record until 2022 when it was broken by Cindy Sember. She is also a two-time medallist over 60 m hurdles at the World Indoor Championships.

She is the sister of Cindy Sember, another elite-level sprint hurdler with dual British and American nationality; Sember, too, chose to represent Great Britain internationally. Unlike Porter, Sember had never represented the United States as a junior. Both sisters made the final of the 100 metre hurdles at the 2016 Summer Olympics.
