Amaiur Sarriegi Isasa (born 13 December 2000) is a Spanish professional footballer who plays as a forward for Real Sociedad and the Spain national team.

In the summer of 2017 she signed for Athletic Club and was assigned to their B-team, also competing in the second tier, where she remained for three years with a consistent scoring return of more than 10 goals in each of the seasons played with the reserves.

[10] Having never been called up at any youth level, Sarriegi made her debut for the Spain national team on 10 June 2021, coming on as a substitute for Marta Cardona against Belgium.

[13][14] She was one of 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 among the dozen who were not involved 11 months later as Spain won the World Cup.

[15][16] 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 and scoring once.
