List of double centuries scored on first-class cricket debut

In cricket, a century is a score of 100 or more runs in a single innings by a batsman. Scores of more than 200 runs are still statistically counted as a century, although these scores are referred to as double century (200–299 runs). A double century is regarded as a landmark score for batsmen and a player's number of double centuries are generally recorded in their career statistics. First-class cricket, the longest version of the game after Test cricket, involves two innings per side in a match and scheduled to last for up to three or more days. An individual scoring a double century on his first-class debut is considered a notable achievement by critics.

The first player to score a double century on first-class debut is English batsman Tom Marsden, who scored 227 runs in the second innings. He achieved the feat on 26 July 1826, while playing for Sheffield & Leicester, against Nottingham during the 1826 English cricket season. English batter David Sales made 210 runs in the third innings, while playing for Northamptonshire on 27 July 1996, against Worcestershire during the 1996 County Championship. He did this at the age of 18 years 234 days, becoming the youngest player to score a double hundred on first-class debut, and also in the County Championship. Sakibul Gani of Bihar claimed the highest individual score in an innings on first-class debut till date, scoring 341 runs against Mizoram, on 18 February 2023, during the 2022–23 Ranji Trophy. With this, he also became the first cricketer to hit a triple century on first-class debut. Hanif Kunrai of Kunar Province scored 200 runs off 189 balls, recording the fastest double century in an innings on first-class debut. He set the record on 17 February 2023, while playing against Kandahar Province, during the 2018–19 Mirwais Nika Provincial 3-Day. The highest unbeaten score on first-class debut till date is 267, which has been achieved by Ajay Rohera of Madhya Pradesh in December 2018, against Hyderabad. Indian batsman Gundappa Viswanath made 230 runs on his first-class debut, for Mysore against Andhra in the 1967–68 Ranji Trophy. He also scored 137 runs on his Test debut, against Australia, on 20 November 1969. With this, he became the first and only cricketer to score a double century on first-class debut as well as a century on Test debut.

The feat has been accomplished by 25 players on 25 occasions as of December 2023. No batter has been able to score a double hundred in both innings on first-class debut so far. Mike Powell's score of 200* for Glamorgan against Oxford University, in June 1997, is the first and only instance of a player achieving the landmark on a losing cause. 13 players from India have reached the milestone so far, the most for any country in the history.
