Masour Ousmane Dembélé (উসমান দেম্বেলে) is a French professional footballer who plays as a striker or winger for Ligue 1 club Paris Saint-Germain and the France national team. Regarded as one of the best players in the world, he is known for his chance-creating and dribbling.

Dembélé began his career at Rennes and was awarded the Ligue 1 Young Player of the Year In his only season with the club. He joined German side Borussia Dortmund in 2016 and won the DFB-Pokal with Dortmund in his debut season, scoring a goal in the final. One of the most prodigious talents in the world, Barcelona signed him for an initial fee of €105 million in the summer of 2017, becoming at the time the joint-second most expensive footballer ever, alongside compatriot Paul Pogba. Despite falling widely short of the expectations for him at Barcelona, Dembélé attained three La Liga, two Copa del Rey, and two Supercopa de España titles.

Dembélé was born in Vernon, Eure, in Normandy. His mother is Mauritanian-Senegalese from Waly Diantang, while his father is Malian. He took his first footballing steps in nearby Évreux, first at ALM Évreux and then at Évreux FC 27 between the ages of 12 and 13.

Dembélé was called up to the senior France squad for the first time in August 2016 to face Italy and Belarus in friendlies after Alexandre Lacazette and Nabil Fekir withdrew through injury. He made his debut on 1 September against the former at the Stadio San Nicola, replacing Antoine Griezmann for the final 27 minutes of a 3–1 win. On 13 June 2017, Dembélé scored his first goal for France in a 3–2 friendly victory against England.

On 17 May 2018, Dembélé was named in the 23-man French squad for the 2018 FIFA World Cup in Russia. On 15 July, he was an unused substitute as France beat Croatia 4–2 in the final.

Dembélé is a winger who can play on either flank, due to his ability to use both feet, and to utilise his technical ability, speed, and agility in order to get past opponents or beat defenders in one-on-one situations. Dembélé can also operate as a left or right-sided attacking midfielder in a 4–4–2 or 3–5–2 formation. His clinical finishing and eye for goal also allow him to be deployed in a more offensive role as a striker. Dembélé also has great quality in terms of his shooting ability from distance.

Dembele is a practising Muslim. He married a Moroccan woman in a traditional Moroccan ceremony in France in December 2021. They have a daughter, born September 2022.

In July 2021, video footage of Dembélé along with teammate Antoine Griezmann circulated online, in which he was seen making racial comments against the Japanese technicians in their hotel room. As the technicians appeared to be troubleshooting the room's television, Dembélé made comments towards Griezmann in French, stating "All these ugly faces, just so you can play PES, aren't you ashamed?", continuing with "What the fuckin language?" before zooming in while laughing on one of the technicians' faces, mentioning "Are you technologically advanced in your country or not?".
