Naseem Shah (নাসিম শাহ) is a Pakistani international cricketer. In October 2019, at the age of 16, he was called up to the Pakistan cricket team for their Test series against Australia. He made his international debut for Pakistan in November 2019 against Australia, becoming the ninth-youngest player to make his debut in Test cricket. In December 2019, in the second Test match against Sri Lanka, he became the second youngest bowler to take a five-wicket haul in a Test match, and also the youngest pace bowler to do so. In February 2020, in the first Test against Bangladesh, he became the youngest bowler to take a hat-trick in a Test match.

Naseem hails from Mayar Jandool, a town in the Lower Dir district of Khyber Pakhtunkhwa province, Pakistan and was born into a Pashtun family.

His father, Abbas Shah, was against his decision to play cricket, preferring him to concentrate on his studies. Naseem eventually completed his education to the tenth grade following which his father wanted him to seek employment abroad. His mother died in 2019, just a day before his Test debut at the age of 16.

After playing tape ball cricket for a few years in Lower Dir, Naseem began his professional journey at the age of 13 when his uncle enrolled him in the Abdul Qadir Cricket Academy in Lahore, where he would be coached by Sulaman Qadir, before getting selected for the Lahore Under-16 team at the age of 13 and later for the Pakistan Under-16 team at the age of 14.

In October 2019, he was named in Pakistan's Test squad for their series against Australia. In November 2019, he played in the three-day warm-up match for Pakistan against Australia A. He made his Test debut for Pakistan, against Australia, on 21 November 2019. His debut was appreciated by many senior cricketers, such as former Pakistan fast bowler Waqar Younis and former England captain Michael Vaughan, the latter being impressed by the 16-year-old touching 147  km/h, or 91.3  mph, in his first ever over. The following month, he was named in Pakistan's Test squad for the two-match series against Sri Lanka. In the second match, he took his first five-wicket haul in Test cricket. At the age of 16 years and 307 days, he became the youngest fast bowler, and the second-youngest among all bowlers, to take a five-wicket haul in a Test match.
