Mohammad Alirezaei Dizicheh (Persian: محمد علیرضایی دیزیچه, born 27 July 1985 in Esfahan) is an Iranian former breaststroke swimmer. Alirezaei became the first Iranian ever to qualify for an Olympic swimming event without using wildcard, when he qualified for the 2008 Summer Olympics. However, he withdrew from the race minutes before he was scheduled to compete against an Israeli. According to team officials, Alirezaei fell ill before the qualifiers for the men's 100 meter breaststroke, and was taken to a hospital in Beijing.
