Ladonnis Decurtis Crump (born June 2, 1984), better known by the stage name Donnis, is an American rapper based in Atlanta, Georgia. He released his debut mixtape, Diary of an ATL Brave, in 2009, and signed to Atlantic Records in 2010.

Donnis was born on June 2, 1984 in Montclair, California before moving to Atlanta. His inspiration to begin rapping was sparked by listening to Kris Kross, Kilo Ali, and the Dungeon Family while he was younger. He started to create and craft his own rhymes at the young age of 9 years old. After high school he joined the Air Force and was stationed in Tokyo, Japan. While on base he began performing and recording music, earning spots opening for such acts as T.I., Chingy, 112, and Erykah Badu. After about 2 1/2 years in the Air Force, he stopped so he could finally pursue rapping as a full on career. Donnis stated in an interview with Amanda Bassa that his time in Japan helped to influence his sound and help him craft it into something a little bit different. Being around an entire new culture gave his sound a bit of an edge; saying that, "The Japanese are always a few steps ahead, that's why I love looking to them for what's next." .
