Rachel Furness (born 19 June 1988) is a former professional footballer. Born in England, she is the record goalscorer for the Northern Ireland national team.

Furness attended Usworth Comprehensive School and represented Durham at County level. By season 2002–03 she was already playing for Chester-le-Street Ladies, alongside several other youngsters and former England striker Aran Embleton.

In 2004 Furness moved to Gateshead College to study sports development and fitness. She began playing for the women's football academy at the college and Sunderland. Jill Scott was a teammate in both sides.

In 2006 Furness moved to Northumbria University to study sports development with coaching, and swapped Sunderland for Newcastle United. However, she had by then suffered a serious knee injury, which required two operations and the removal of most of the cartilage. Doctors advised Furness to stop playing football but she nevertheless resumed playing for Newcastle United.

In December 2009, Furness scored one and made the other for Mel Reay, as Newcastle drew 2–2 at OOH Lincoln Ladies in the FA Women's Cup, only to miss her penalty in the shootout defeat.

Furness spent the 2010 summer season in Iceland with Grindavik, then rejoined Sunderland – making her second debut for the club in a 4–0 Premier League Cup win over Newcastle in October 2010. After helping Sunderland win the Premier League title, Furness joined FA WSL club Lincoln Ladies on loan. She made a quick debut in Lincoln's 1–0 home defeat to Chelsea in May, the last game before the WSL mid–season break. She returned to parent club Sunderland before the WSL restarted in July.

In January 2017, Furness left Sunderland for Reading shortly after the Lady Black Cats reverted to part-time status.

Furness joined Tottenham Hotspur on a season-long loan from Reading on 6 September 2019. On 28 December 2019, Furness joined Liverpool, after being recalled by Reading.
