Barrum is a hamlet in the Dutch municipality of Waadhoeke in the province of Friesland.

It is located south of Tzum, of which it is a part administratively.

It lies directly to the north of the hamlet of Koum [nl].

[4] On a map by Schotanus from 1664 it was mentioned as Barzum,[5] yet this could be a confusion with another hamlet, located a little more south, Barsum [nl].

In 1850 the place was referred to as Barrum, and it is estimated that around that time, 14 people were living in the two farms of the hamlet.
