Ouwegem is a village and deelgemeente (sub-municipality) in the municipality of Kruisem in the province of East Flanders in Belgium.

The village is located on the edge of the Flemish Ardennes and about 17 kilometres (11 mi) south-west of Ghent.

[2] The village was first mentioned in 830 as "villa Aldinga-heim", and means "settlement of the people of Aldo (person)", but artefacts and coins have been recovered in the area from the Roman era.

Ouwegem became a village heerlijkheid (landed estate), however there were other smaller heerlijkheden in the area.

[5] In 2019, it was merged into the municipality of Kruisem,[6] but remains a deelgemeente (sub-municipality).
