Hatsum or Hatzum (Dutch pronunciation: [ˈɦɑt.sʏm]) is a hamlet in the Dutch municipality of Waadhoeke in the province of Friesland. It is located north of Baaium and south of Dronryp, of which it is a part administratively.

The mainly dispersed residences of the hamlet are located on the roads Longbuorren, Hatzum, Keimptilsterdyk and a part of Rewertdyk (up to the Molensloot). The residences on the Dykshoek on the Van Harinxma Canal [nl] are also included in the hamlet, even though it actually belongs to the Kingmatille hamlet. The Hatsumer Opfeart also flows through the hamlet.

Built on a terp, the hamlet was first mentioned in 1511 as Hastzen, in 1531 as Hatsem and in 1543 as Hatzum. On the southeastern side of Baaium was also a place of the same name, which was mentioned in 1511 as Hastzen as well. It was a large farm that was referred to as Lamkema in the 17th century, later found as a field name as Hatsem. Given the proximity, it may be directly connected. It is assumed that the place name refers to the fact that it is a place of residence (-heem/-um) of or founded by the person Hette.

A double train track also runs through the hamlet and it therefore has a train station, Dronryp railway station. There is also a restaurant, currently called Op Hatsum. On the Hatsumeropvaart near Kingmatille is a windmill of the same name, Kingmatille which has been on that spot since 1987, and near the railway is the Hatsumermolen.
