Herbaijum (West Frisian: Hjerbeam) is a village in Waadhoeke municipality in the province Friesland of the Netherlands and had around 253 citizens in January 2014.

[4] The village was first mentioned in the 13th century as Herbadingum, and means "settlement of the people of Herbad (person)".

One of the inhabitants was Sicco van Goslinga, grietman (mayor/judge) of Frankeradeel and curator of the University of Franeker.

[4] The church was built in the Middle Ages; general estimates point to establishment around the second half of the 13th century.

The tower on the west side was probably built in the 1920s, and has a constricted, octagonal spire and is roofed with slate tiles.
