1920 Haiyuan earthquake (Chinese: 海原大地震; pinyin: Hǎiyuán dà dìzhèn) occurred on December 16 in Haiyuan County, Ningxia Province, Republic of China. It was also called the 1920 Gansu earthquake because Ningxia was a part of Gansu Province when the earthquake occurred.

The earthquake hit at 20:05:53 Beijing time (12:05:53 UTC), reportedly 7.8 on the Richter magnitude scale, followed by a series of aftershocks for three years. Today's Chinese media claim the earthquake was of magnitude 8.5, although the scale is not specified. It caused total destruction (XII (Extreme) – the maximum intensity on the Mercalli scale) in the Lijunbu-Haiyuan-Ganyanchi area.

Total casualties were reported as 200,000 in a summary published by the United States Geological Survey (USGS), and 235,502 according to the Catalog of Damaging Earthquakes in the World (Through 2008) maintained by the International Institute of Seismology and Earthquake Engineering. Many more perished because of cold: frequent aftershocks caused the survivors to fear building anything other than temporary shelters, and a severe winter killed many who had lived through the original earthquake.

The Sufi Jahriyya Muslim Hui leader Ma Yuanzhang and his son died in the earthquake when the roof of the Mosque they were in collapsed in Zhangjiachuan.
