Williamsonia is a genus of small dragonflies in the family Corduliidae. They are commonly known as boghaunters. Unlike other genera of emerald dragonflies, they have dark eyes and nonmetallic bodies.[1]

The genus consists of only two living species:[2]

Williamsonia fletcheri Williamson, 1923 – ebony boghaunter[1][3]
Williamsonia lintneri (Hagen in Selys, 1878) – ringed boghaunter[3]
