Amad Diallo (আমাদ দিয়ালো), sometimes known mononymously as Amad, is an Ivorian professional footballer who plays as a winger or attacking midfielder for Premier League club Manchester United and the Ivory Coast national team. A versatile player, he has also been deployed as a wing-back.

Born in the Ivory Coast, Amad moved to Italy as a child. He joined the Atalanta youth system in 2015, where he won two Campionato Primavera 1 titles. In 2019, he scored on his debut for the senior team. In January 2021, Amad joined Manchester United, and had loan spells at Rangers and Sunderland.

Born in Abidjan, Ivory Coast, Amad emigrated to Italy at a young age. He started out at Boca Barco's youth team in September 2014, where he impressed at a Christmas tournament the same year; he was the tournament's top goalscorer as the youngest on the field. Amad was officially registered to the team on 14 January 2015.

Amad was first called up to the Ivory Coast national team on 18 March 2021 for their 2021 Africa Cup of Nations qualification matches against Niger and Ethiopia on 26 and 30 March, respectively. He made his debut against Niger, coming on as an 86th-minute substitute. On 5 June 2021, Amad scored his first international goal in a friendly against Burkina Faso, through a 97th-minute free kick, to help his team win 2–1 at home.

On 3 July 2021, Amad was named in the Ivory Coast under-23 team for the 2020 Summer Olympics. Amad made his Olympics debut, and assisted a goal, in a 2–1 win against Saudi Arabia on 22 July. He made four appearances at the tournament.

A winger who is also capable of playing as a mezzala, Amad is a quick and dynamic player with a high technical ability and a good vision of the game. The fact that he is two-footed makes him a versatile player. He is capable of both creating chances and cutting inside mainly from the right flank, even playing as a right wing-back under Ruben Amorim. Amad possesses quick acceleration and dribbling skills, often dribbling using small touches on the ball and taking on defenders rather than bursting into space. He is known to perform back-heel passes and other tricks.

In July 2020, an investigation into the trafficking of football players was launched by the public prosecutor's office of Parma. Among the involved was Hamed Mamadou Traoré, a distant relative of Amad and his alleged brother Hamed Traorè, who was accused of posing as their father to facilitate their immigration into Italy. The investigation also questioned the relationship between Amad and Hamed.

On 9 February 2021, Amad was found guilty of violating the Italian Sports Justice Code to join the football club "ASD Boca Barco" in 2015 under the name "Diallo Amad Traoré". He was accused of falsifying documents to fake a relationship with Hamed Mamadou Traoré, an Ivorian citizen resident in Italy, and request a family reunification. Amad requested a plea bargain, with the Federal Prosecutor's Office imposing a fine of €48,000.

Diallo received his Italian passport in December 2020.

On 11 July 2020, the day of his 18th birthday, Amad changed his Instagram name from "Amad Traoré" to "Amad Diallo", with a caption reading "don't call me Traoré anymore". In September 2020, his name was legally changed to Amad Diallo.
