Hamza Riazuddin (Urdu: حمزہ ریاض الدین; born 19 December 1989) is an English former cricketer.

Riazuddin was educated at Crosfields School in Shinfield, before attending Bradfield College, where he was coached by the former cricketer Julian Wood.

[2] Riazuddin captained the England under-19 cricket team in both Youth Test and One Day Internationals in 2008 and 2009.

[7][8] He was rarely chosen to play first-class cricket, but did make four appearances in the 2012 County Championship,[6] with Riazuddin taking his only five wicket haul (5 for 61) against Glamorgan, a match in which he hit Hampshire's winnings runs.

[10] Once considered as a long-term replacement for Dimitri Mascarenhas, Riazuddin found his opportunities at Hampshire limited and subsequently left at the end of the 2013 season.
