Dantumadiel () is a municipality in the province of Friesland in the Netherlands. Dantumadiel is a rural municipality characterized by economic activity and agriculture.
The first time Dantumadiel is mentioned was in a document from 1242. At that time Dantumadiel, or Donthmadeil as it was then known, was a part of the Winninghe district, the northern part of Oostergo. The grietenij (municipality) Dantumadiel was led by a grietman (mayor) who was holding office in Rinsumageast and Dantumawâld. The Dutch Municipalities Act of 1851 (Dutch: Gemeentewet van 1851) abolished the grietenijen, which automatically became gemeenten (municipalities) headed by a mayor.
