Davidson Ezinwa (born 22 November 1971) is a former sprinter from Nigeria. He won a silver medal at the 1992 Summer Olympics as well as a silver medal at the 1997 World Championships, both in 4 x 100 metres relay. He also won a 60 metres silver medal at the 1997 World Indoor Championships. In 100 metres his personal best time is 9.94 seconds, although he has recorded 9.91 s, albeit with a doubtful wind reading of -2.3 m/s which is an unlikely weather condition for records. In any case his result ranks him second in Nigeria, behind Olusoji Fasuba, and third in Africa, behind Fasuba and Frankie Fredericks. His personal best 200 metres time is 20.30 seconds, from 1990. Ezinwa established a new World junior record in the 100-meter dash in 1990 (10.05), breaking Stanley Floyd’s ten-year-old record (10.07). Ezinwa’s record was not broken until 2003, when Darrel Brown ran a 10.01 100-meter dash. He is the older twin brother of Osmond Ezinwa. Both attended the Christian university Azusa Pacific University. Davidson Ezinwa tested positive for doping twice; for ephedrine in February 1996, and together with Osmond for hCG in 1999.
