The village was first mentioned in 855 as Coluuidum, and means "charcoal woods". Koudum developed on the higher clay ground in the Gaasterland region. It used to be a linear settlement with a little centre around the church. Koudum was the capital of the former municipality of Hemelumer Oldeferd [nl] until 1984.

Between 1614 and 1617, a church was built with a 60 metres (200 ft) high tower, however both the church and tower were replaced by a new church in 1857 with a more modest tower.

Koudum was home to 925 people in 1840. Before 2011, Koudum was the seat of the former municipality of Nijefurd. Before 1984, it was part of Hemelumer Oldeferd municipality.
