Jillian Anne Ellis (born 6 September 1966) is an English-American football coach. She coaches the United States women's national soccer team and is the development director of the United States Soccer Federation, overseeing the national youth teams development program. In 2015 and 2019, the United States Women's National Soccer Team won the World Cup Championship under her leadership making her the second coach winning a world cup back to back. Ellis was appointed head coach on 16 May 2014. Prior to this appointment, she served as interim head coach following the removal of Tom Sermanni on 6 April 2014, having previously held the position upon Pia Sundhage's early departure in October 2012. She has also served as head coach for various college and United States national youth teams over the years.
Ellis did not play organized soccer until her family moved to the United States in 1981, as there was no organized football for girls in the UK in the 1970s. She captained the Robinson Secondary School team in Fairfax, Virginia to the 1984 state championship and won the under-19 national title with the Braddock Road Bluebelles the same summer.
