Hasan Ali (হাসান আলী) is a Pakistani cricketer who plays for the Pakistan national team in all formats. He made his first-class debut for Sialkot in October 2013. He made his international debut for Pakistan in August 2016 in a One Day International (ODI) match against Ireland. The following summer, he was named in Pakistan's squad for the 2017 ICC Champions Trophy. Pakistan went on to win the tournament with Ali named player of the tournament after taking thirteen wickets, and took the final wicket of Jasprit Bumrah. He became the quickest bowler for Pakistan to take 50 wickets in ODIs. In August 2018, he was one of thirty-three players to be awarded a central contract for the 2018–19 season by the Pakistan Cricket Board (PCB).

Hasan Ali was born into a Punjabi Jat family of the Malhi clan to Abdul Aziz Malhi, whom Ali considers a source of inspiration for his life. He was born in a village near Mandi Bahauddin . His family encouraged him to play cricket from an early age. Two local cricketers, his elder brother Ata-ur-Rehman (not to be confused with the former international cricketer) and Ansar Zafar Rathore, were his childhood coaches and mentors.

Ali trained at Rathore's Young Combine Star Club in Gujranwala, where other international cricketers have also trained, including Imran Nazir. Ali's coaching began at the age of 10 and, considering his rapid progress and his physical fitness routine (up to eight hours a day everyday in a dedicated gym), by the age of 14 he was selected for the city's U16 side.

In August 2016, Ali was added to Pakistan's One Day International (ODI) squad for their series against England and Ireland. He made his ODI debut for Pakistan against Ireland on 18 August 2016. He made his Twenty20 International debut for Pakistan against England on 7 September 2016.

Ali took his first five-wicket haul in ODIs against Australia on 22 January 2017. In April 2017, Ali was added to Pakistan's Test squad for their series against the West Indies. He made his Test debut for Pakistan in the third Test against the West Indies on 10 May 2017.
