Dadi Yami Gemeda (born 1982) is an Ethiopian long-distance runner who competes in the marathon. His personal best for the distance is 2:05:41 hours. Born and raised in the rural areas to the north of Addis Ababa, Dadi's birth date is unknown due to poor record keeping and is estimated to be in 1982. He began working with athletics manager Jos Hermens and began training for the marathon with his group. He made his debut over the distance at the 2011 Eindhoven Marathon and managed ninth place with a time of 2:11:04 hours. The 2012 Dubai Marathon saw him make a significant breakthrough with a run of 2:05:41 hours. In the extremely fast race, this was only enough for sixth place, but still ranked him in the top twenty in the world that year and in the top forty on the all-time lists.
