Oudenburg (Dutch pronunciation: [ˈʌudə(m)ˌbʏr(ə)x]; French: Audembourg [odɑ̃buʁ]; West Flemish: Oednburg [ˈʊdn̩bœrh]; Latin: Aldenburgensis) is a city and municipality located in the Belgian province of West Flanders. The municipality comprises the city of Oudenburg itself and the towns of Ettelgem, Roksem and Westkerke. On January 1, 2006 Oudenburg had a total population of 8,929. The total area is 35.38 km² which gives a population density of 252 inhabitants per km².

Oudenburg is situated on the location of a Roman castellum built in the 4th century, whose outline is still visible in the city's streetplan. Some of the stones of the former walls were later used in the construction of the abbey. The former abbey of St. Peter at Oudenburg, founded by Arnold of Soissons, was destroyed during the French Revolution.

The castle already appeared on the oldest seal of the city, dating from 1226. All later seals showed a castle, but the size and shape of the castle has changed considerably through the centuries. The small shield appeared for the first time in the 16th century.
