The 1916–1917 Nantou earthquakes (Chinese: 1916年南投地震系列; pinyin: 1916 nián Nántóu dìzhèn xìliè) affected central Taiwan in 1916 and 1917, causing heavy damage in sparsely populated Nanto Chō (modern-day Nantou County) and claiming 71 lives.

The strongest quake registered at 6.8 ML and besides the loss of life caused widespread damage to agricultural and forestry industries in central Taiwan.

The first major quake, on 28 August 1916, was the strongest at magnitude 6.8, but the hypocentre was relatively deep in the Earth's crust.

The most deadly quake in the series came on January 5 of the following year, registering at 6.2 on the Richter scale with a shallow hypocentre, killing 54 people.

[1] Seismometers were installed in the area in 1898 shortly after the Japanese took control of Taiwan, but there was relatively little seismic activity in Nantou between then and 1916.
