Caroline Elspeth Lillias Weir (born 20 June 1995) is a Scottish professional footballer who plays as an attacking midfielder or forward for Spanish Liga F club Real Madrid CF and the Scotland national team.

Weir made her full international debut in 2013, and played for Scotland at the UEFA Euro 2017 and 2019 FIFA World Cup tournaments.

[3] In 2011, she won the SWFL First Division player of the year award for her performances in Hibs' reserve side while also making her first team debut in May against Glasgow City.

[23][24] Shortly after that, a statement was released about a "hold on processing of non-EU licences", affecting the signing of Weir, who was not registered with Real Madrid before 30 June.

[25] A month later she scored a goal that knocked her previous club Manchester City out of Champions League qualifying and enabled Madrid to progress the second phase.

Shortly after her return from the injury in October 2024, she "curled in a brilliant opener from distance" to open the scoring in a 2024–25 UEFA Women's Champions League fixture against Celtic which Real Madrid won 4–0;[28] it was the first time she had played a club match against a Scottish team since Arsenal defeated Glasgow City in the 2013–14 edition of the same tournament,[29] a few months after Weir left Hibernian for the English league.

During Euro 2017, the first major tournament for which Scotland had qualified, Weir scored the opening goal against Spain and was voted player of the game.
