Hamis "Diego" Kiiza (born 10 December 1990) is a Ugandan professional footballer who plays for Kagera Sugar FC in Tanzania premier league.
Diego made his Cranes debut for Bobby Williamson in May 2011 when he was called up for the U23 side to face Tanzania in an All Africa Games Qualifier. He repaid the faith shown in him with 3 goals in 2 games against Tanzania and helped the team to the next round to face Kenya.[2] After his impressive displays for the U23 side, he was promoted to the full National Team that will take on Guinea-Bissau in the crucial 2012 African Cup of Nations qualifier on 4 June 2011.[3]
