Christopher Alan Nkunku (ক্রিস্টোফার এনকুনকু) is a French professional footballer who plays as a forward, second striker or attacking midfielder for Premier League club Chelsea and the France national team.

Nkunku is a graduate of the Paris Saint-Germain Academy and made his professional debut for the club in December 2015. He made 78 appearances for them and won three Ligue 1 titles, the Coupe de France twice and the Coupe de la Ligue twice. Nkunku joined German side RB Leipzig in July 2019, with whom he scored 70 goals in 172 appearances over four seasons and won the DFB-Pokal twice. He was named the Bundesliga Player of the Season in the 2021–22 campaign and was the league's top scorer the following season. Nkunku was signed by Chelsea in 2023 for £52 million.

Christopher Alan Nkunku was born on 14 November 1997 in Lagny-sur-Marne, Seine-et-Marne. He went to El Francis Assis Secondary school and he began playing football with AS Marolles as a six-year-old. In 2009, he joined Fontainebleau, where he was spotted by scouts of several professional clubs. Despite his young age and childlike physique, he was noted for "his speed, his technique and his vision of the game", as recalled by Norbert Boj in 2020, former head of the Fontainebleau football school. He would line up in all positions across the midfield, a versatility he, according to another coach at the club, owed to his "technical prowess, obviously, but especially his intelligence of play".

Nkunku was born in France and is of Congolese descent. He was a French youth international, representing the country at under-16, under-19, under-20 and under-21 levels. He made three appearances for the under-20 team at the 2017 FIFA U-20 World Cup.

Nkunku was called up to the senior France squad for the first time for friendly matches against Ivory Coast and South Africa on 25 and 29 March 2022, respectively. He made his debut as a starter in the game against Ivory Coast. On 9 November 2022, he was named in the 25-man French squad for the 2022 FIFA World Cup in Qatar. On 15 November, he sustained a knee injury after colliding with Eduardo Camavinga during training at Clairefontaine, which forced him to drop out prior to the competition.
