Nicolas Jackson (নিকোলাস জ্যাকসন) is a professional footballer who plays as a striker for Premier League club Chelsea and the Senegal national team.

Jackson played for Casa Sports in Senegal before joining Villarreal in 2019. After a loan to Mirandés in the Segunda División, he broke through in the reserve team and made his first-team debut in La Liga in 2021. In 2023, he signed an eight-year deal at Chelsea for a reported fee of £32 million.

Nicolas Jackson was born in Banjul, The Gambia, in 2001, to a Gambian father and Senegalese mother. In 2017, in the aftermath of the 2016 Gambian presidential election, the family moved to Ziguinchor, Senegal.

Jackson represented Senegal at under-20 level, receiving his first call-up in November 2018.

After being called up to the full side by manager Aliou Cissé for two friendlies in September 2022, Jackson was included in the 26-man list for the 2022 FIFA World Cup on 11 November 2022. He made his full international debut in Senegal's opening match of the competition, replacing Krépin Diatta in a 2–0 loss against the Netherlands.

In December 2023, Jackson was named in Senegal's squad for the postponed 2023 Africa Cup of Nations held in the Ivory Coast. He came on as a substitute in all four games as the defending champions made it to the last 16.
