JustD (English: Just that) was a Swedish hip hop trio formed in Stockholm in 1990. The group consisted of Gustave Lund (Gurra G), Wille Crafoord (Doktor C) and Peder Ernerot (Pedda P). They had several chart successes during the early-mid 1990's.

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.
