Samiur Rahman was born in Dacca on 3 December 1953 and played international cricket before moving into officiating. As a player, he appeared for the national side in the first half of the 1980s as a right-arm fast-medium bowler and right-handed lower-order batsman. He took part in Bangladesh in its first-ever One Day International match against Pakistan in Moratuwa in 1986. Across his two ODI appearances, he scored four runs at an average of two and bowled sixty wicketless deliveries while claiming one catch.
Beyond his two ODIs, Rahman represented the national side in other limited-overs fixtures. He missed selection for the inaugural 1979 ICC Trophy but returned for the 1982 tournament where Bangladesh finished fourth. During that 1982 campaign, he captured seven wickets at an average of 18.85, highlighted by figures of 3/31 against West Africa. He later played three matches and took three wickets during the 1986 fixtures.
After concluding his playing days, Rahman transitioned to officiating within domestic cricket. He served as a Bangladesh Cricket Board umpire for over one hundred matches. Alongside his time on the field with the whistle, he also worked as a match referee across 25 T20 matches.
Rahman died on 19 April 2022. Prior to his death at the age of 68, he had been ill for two years following a brain tumour diagnosis and other health complications.
