Just D is a now non-active Swedish hip hop trio that consisted of Gustave Lund (Gurra G), Wille Crafoord (Dr. C) and Peder Ernerot (Pedda Pedd)

Their contribution to the Swedish hip hop scene is significant because they were the first successful Swedish language rap act. Their dominance in the Swedish charts during the early 1990s opened up a new market in the Swedish music scene for artists who wished to record rap music in Swedish. Previously, prior to the success of Just D, Swedish rap artists used English rhymes in a bid to succeed in the international market. Just D showed that local chart success with Swedish rhymes was a lucrative market in and of itself.

Just D were marketed like the early incarnation of the Beastie Boys and they had the same impact on Swedens popular music audience. They applied American hip hop rhythm & rhyme to Swedish pop music and their formula made hip hop trendy and palatable to new audiences. Just D's presentation of rap music had a certain irony and some might say parody to it. In contrast to the majority of Swedish hip hop artists in the 1990s, none of the members in Just D had an immigrant background, which according to some contributed to their marketablity to the Swedish public. Their lyrics referred to förortsdjungeln (the suburban jungle) i.e. Swedish immigrant-dominated working-class suburbs, however, the members of Just D came from affluent homes, and Wille Crafoord is a member of the Swedish nobility. However, when the next wave of Swedish language rap music came, Swedish audiences had become ready for the rhymes of The Latin Kings, Infinite Mass, Petter, Blues and Feven.
