Def Dames Dope (DDD) was a girl group from Belgium during the 1990s, most successful from 1993 to 1996. They released one more single in 2002.

The group was initially made up of the two sisters Larissa and Axana Ceulemans together with Yousra Lemaire (nicknamed TRS). Larissa married Berre Bergen (who played bass guitar with the Belgian band De Kreuners), and left the group. Ingrid Gerits (nicknamed H2O) and Edith Verlinden (nicknamed Tabasco) joined Def Dames Dope. Axana (nicknamed Snake) composed many of the lyrics and music, and the group was a project of techno producers Phil Wilde and Jean-Paul De Coster (better known for his project 2 Unlimited).
