Nerea Eizagirre[a] Lasa (born 4 January 2000) is a Spanish professional footballer who plays as a midfielder for Liga F club Real Sociedad and the Spain women's national team.

[5] She was a member of the group which won the 2018–19 Copa de la Reina and finished as runners-up in the 2021–22 Primera División.

Following some good form for her club including several goals, Eizagirre earned a call-up to the senior Spain squad in October 2020.

[8][9] She was among Las 15, a group of players who made themselves unavailable for international selection in September 2022 due to their dissatisfaction with head coach Jorge Vilda, and one of the dozen who were not involved 11 months later as Spain won the World Cup.

[10][11] She has also been selected for the unofficial Basque Country women's national football team which plays only occasionally, making her first appearance in December 2022 against Chile in which she opened the scoring.
