Viktor Einar Gyökeres (ভিক্টর আইনার গিয়োকেরেস) is a Swedish professional footballer who plays as a striker for Primeira Liga club Sporting CP and the Sweden national team.

Gyökeres made his professional debut with Swedish side Brommapojkarna in 2015, making over fifty appearances before joining Brighton & Hove Albion in 2018. Gyökeres went on loan to various clubs, including St. Pauli, Swansea City and Coventry City, joining the latter permanently in 2021.

Gyökeres played youth football for Sweden at under-19 and under-21 level. Gyökeres featured regularly for Sweden in the nation's qualification campaign for the 2017 UEFA European Under-19 Championship during which he scored twice, including the winning goal against Italy to help Sweden qualify for the tournament for the first time. He was then selected for the squad which took part in the tournament in Georgia and scored in all three of Sweden's group matches but was unable to help the nation progress to the knockout stages of the tournament. His return of three goals later saw him share the Golden Boot award with England's Ben Brereton and Ryan Sessegnon, and the Netherlands' Joël Piroe.

On 8 January 2019, Gyökeres made his senior international debut for the Sweden men's national football team in a 1–0 loss against Finland. Three days later, Gyökeres scored his first senior goal for Sweden in a 2–2 draw against Iceland. In October 2021, after scoring 9 goals in 11 EFL Championship games for Coventry, Gyökeres was called up to the Sweden national team to replace Zlatan Ibrahimovic to face Kosovo and Greece for the 2022 World Cup qualifiers. On 16 October 2023, Gyökeres had given Sweden a 15th-minute lead before Romelu Lukaku equalised in an away game against Belgium, when the UEFA Euro 2024 qualifier was abandoned at half-time following a Islamist-related fatal shooting in Brussels that targeted and killed two Swedes outside the stadium.

Gyökeres is known for his physicality, pace and stamina, using his acceleration to exploit space behind defenders and his strength to act as a target man in aerial duels and ground battles. He excels in both aerial duels and on the ground, using his strength and size to shield the ball and link play, often contributing by running the channels or delivering crosses, while also being capable of creating chances through sharp turns and flicks in one-on-one situations. His pressing ability, helps him disrupt opposition build-up and force defensive mistakes, helping also in set-piece situations.

Gyökeres is of Hungarian descent through his paternal grandfather who emigrated to Sweden, and is a dual citizen of Hungary and Sweden. His father Stefan Gyökeres played football for IFK Östersund and Stugun in the 1980s and 1990s.

Broadcaster CMTV reported in January 2024 that Gyökeres was in a relationship with Portuguese actress Inês Aguiar. He was formerly in a relationship with fellow professional footballer Amanda Nildén, whom he met in high school, and who joined the Brighton women's team when Gyökeres moved to the club in 2018.
