Su Jun (died 328) was a Jin Dynasty (265–420) general, whose rebellion against Emperor Cheng's regent Yu Liang is initially successful, allowing him to take over the imperial government, but he is eventually defeated by Tao Kan and Wen Jiao's forces and killed in battle.

The disturbance he had created greatly weakens the Jin regime, which for decades will have no ability to fight back against rival Later Zhao.
