Alejandro Balde Martínez (born 18 October 2003) is a Spanish professional footballer who plays as a left-back for La Liga club Barcelona and the Spain national team.

[11] On 14 September 2021, he played his first official match for Barcelona's first team replacing Alba in the 74th minute of a 3–0 loss to Bayern Munich in the group stage of the UEFA Champions League.

[15] On 24 January 2024, he suffered a hamstring injury in his right foot, and had to undergo surgery after leaving the pitch in tears against Athletic Bilbao in the Copa del Rey quarterfinals, which Barcelona lost 4–2, and Balde ended up missing the rest of the season.

He received a surprise call-up to the Spain national team two days before the start of the 2022 FIFA World Cup, as Valencia left-back José Gayà had injured his ankle in the training camp.

[18][19] Balde's speed and agility allow him to recover effectively in defensive phases, while his composure on the ball has made him a reliable outlet for build-up play.
