Yusuf Saad Kamel (), born Gregory Konchellah (born 29 March 1983) is a male former middle-distance runner who competed in the 800 metres and 1500 metres. Born in Narok, Kenya – the son of former two-time 800 metres World Champion Billy Konchellah – he represented Bahrain internationally. Kamel won the gold in the 1500 m and bronze in 800 m at the 2009 World Championships in Athletics held in Berlin. In early 2009 he stopped competing for Bahrain claiming unpaid salary and bonuses. He was willing to compete for Kenya, but his Kenyan passport was held by Bahraini officials. Without a passport, he was unable to compete in any competition. Several other Kenyan runners who took Bahraini citizenship have also left Bahrain and are vying to compete for Kenya. However, he returned to the track in July 2009 at the Athletissima meeting, still representing Bahrain. Subsequently, Athletics Kenya stopped to handle his attempt to compete for Kenya. At the 2011 World Championships in Athletics in Daegu he only participated at the 1500 m but just failed to qualify for the final. He trained with PACE Sports Management under Ricky Simms.
