Martín Zubimendi Ibáñez is a Spanish professional footballer who plays as a defensive midfielder for La Liga club Real Sociedad and the Spain national team.

Born in San Sebastián, Gipuzkoa, Basque Country, Zubimendi joined Real Sociedad's youth setup in 2011. He had also played for Antiguoko in the Donosti Cup between 2006 and 2013. He made his senior debut with Real Sociedad C on 27 August 2016, playing the last seven minutes in a 0–0 Tercera División home draw against Durango.

Zubimendi represented the Spain under-19s in a friendly 2–1 loss to the Portugal under-19s on 15 November 2017.

Due to the isolation of some national team players following the positive COVID-19 test of Sergio Busquets, Spain's under-21 squad were called up for the international friendly against Lithuania on 8 June 2021. Zubimendi made his senior debut in the match.

Zubimendi's versatile style of play draws comparisons to renowned players, notably Sergio Busquets. He showcases composure and control, guiding plays and adjusting the game's tempo. His role involves initiating plays from deep positions, displaying precise decision-making. Zubimendi's aptitude for receiving passes and creating space is reminiscent of Busquets, reflecting a deep understanding of the game and the art of crafting opportunities. Additionally, his technical abilities, including dribbling and deep runs, align with top midfielders, while his ball retention in tight spaces mirrors qualities seen in players like Xabi Alonso and David Silva.
