History

A post office called Amherst was established in 1887.^[2] The community most likely takes its name from Amherst, Massachusetts.^[3]

Approximately two and half miles southeast of the village a rupture of the Keystone Pipeline caused what is being called the largest oil spill in South Dakota history on November 16, 2017.^[4] The spill is an area about 100 yards in radius within a conservation reserve field about a mile east of 416 Avenue south of the village.^[5]
