Dantumadiel (West Frisian pronunciationⓘ) is a municipality in the province of Friesland in the Netherlands.

Dantumadiel is a rural municipality characterized by economic activity and agriculture.

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.
