Khan Abdur Razzak (Bengali: খান আব্দুর রাজ্জাক; born 15 June 1982) is a Bangladeshi former cricketer who played in all formats of the game.

Best known for being a tall left-arm orthodox spin bowler, he helped guide his division to the National Cricket title in his maiden season.

From there he was selected for Bangladesh A (training team for the full national squad) performing well against Zimbabwe A, including figures of 7 for 17 in one game in Dhaka.

Though he played just nine Tests, was more successful in One Day Internationals (ODIs) and was Bangladesh's leading wicket-taker in the format in 2013, when he reached the 200 wickets milestone.

His match haul of 15/193 against Barisal Division were the best in the history of the National Cricket League, breaking the record set three years previously by Elias Sunny, the bowler who had replaced Abdur Razzak in the Test team.

[12] Abdur Razzak was called into the Bangladesh national team for the 2004 Asia Cup One Day International tournament, making his debut against Hong Kong in July.

After impressing in one-day cricket, he was called up for his Test debut at home to Australia at the Chittagong Divisional Stadium.

Following New Zealand's tour of Bangladesh in October 2008, Abdur Razzak was reported by umpires Daryl Harper and Asoka de Silva for having a "suspect bowling action".

[14] In March 2009, the ICC lifted Abdur Razzak's suspension after he changed his bowling action; now both his stock delivery and faster ball are legal.

Bangladesh lost the match, their first Test since touring England in June the previous year, with Abdur Razzak taking two wickets for 106 runs.

[26] When the West Indies toured in October he went wicketless in the ODI series and was subsequently dropped from the Test squad, which led him to consider the international retirement in 2014.

[3] In March 2020 Razzak was offered a position in the Bangladesh national selection panel however the COVID-19 pandemic delayed his appointment to the role until January 2021.
