Daniel Effiong (born 17 June 1972) is a Nigerian retired sprinter. He became African 100 metres and Universiade champion in 1993. Together with Innocent Asonze, Francis Obikwelu and Deji Aliu he won a bronze medal in 4 x 100 metres relay at the 1999 World Championships, but the team was later disqualified (in August 2005) because Innocent Asonze failed a doping test in June 1999. In 100 metres his personal best time was 9.98 seconds, achieved in the semifinal of the 1993 World Championships. This ranks him sixth in Nigeria, behind Olusoji Fasuba, Davidson Ezinwa, Olapade Adeniken, Francis Obikwelu and Uchenna Emedolu. In 200 metres his personal best time was 20.10 seconds, achieved in May 1994 in Mount Sac. This ranks him second in Nigeria, only behind Francis Obikwelu, and fourth in Africa, behind Frankie Fredericks, Obikwelu and Stéphan Buckland. He missed the 1995 World Championships in Athletics due to a failed drug test at the Nigerian Championships, where he tested positive for methyltestosterone and ephedrine. He received a four-year ban from the sport.
