Willie D (born Willie James Dennis in Houston, Texas, U.S.) is an American rapper who gained fame as the lead member of the pioneering rap group from Houston, Geto Boys. Despite his reputation for being a hardcore artist who pens often provocative lyrics, Willie D is known for his diligent work in the community and many of his songs contain positive messages. He is often called on to speak at universities, high schools and youth facilities.

A gifted athlete, Willie took up boxing at the age of 11. Willie D was so good at boxing that in 1985, he became the Golden Gloves Champion for the State of Texas. With a Golden Glove championship under his 17-year-old belt it looked like Willie D was well on his way to becoming a professional boxer, but fortunately for hip hop fans fate intervened. Like any teenager growing up in the early 80’s Willie D was captivated by the music of his generation. A fan of hip hop, he listened intensely to the music and set his sights on becoming an emcee.

Soon Willie D was earning a reputation around town as a fierce MC. Eventually Willie’s reputation reached J Prince, founder of Rap-A-Lot Records. At the time Prince was looking to revamp the now legendary Geto Boys and knew that Willie D would be a key factor in the group’s success. Once Willie D was on board, Bushwick Bill and Scarface were added to complete the group.

Considered the classic line up, Willie D, Bushwick Bill, and Scarface first emerged as the Geto Boys in 1989 with their Gold record, "Grip It! On That Other Level." The record contained the songs "Gangsta of Love," "Do It Like a G.O.," "Size Ain’t Shit," and "Read These Nikes," all penned by Willie D. Willie went on to record a string of critical and commercially successful solo and group albums including the Geto Boys’ "We Can't Be Stopped" (platinum), which featured the single "Mind Playing Tricks on Me," co-written by Willie D.

In 2009, Willie D was featured on the underground hit "Down South Hustlaz", along with Young Buck, Trae, Bun B, and Rick Ross. He is currently in the studio with Z-Ro recording a new CD presently untitled and is scheduled to release a Greatest Hits CD is June. He is also writing a book about his life.
