The Wanggongchang Explosion (Chinese: 王恭廠大爆炸), also known as the Great Tianqi Explosion (天啟大爆炸), Wanggongchang Calamity (王恭廠之變) or Beijing Explosive Incident in the late Ming dynasty (晚明北京爆炸事件), was a catastrophic explosion that occurred on May 30, 1626, during the late reign of the Tianqi Emperor at the heavily populated Ming Chinese capital of Beijing, and reportedly killed around 20,000 people. The epicenter was a major production center of gunpowder, but it is uncertain exactly what triggered the explosion.
