Brasschaat (Dutch pronunciation: [brɑˈsxaːt] ⓘ) is a municipality located in Flanders, one of the three regions of Belgium, and in the Flemish province of Antwerp.

The village of Brasschaat belonged geographically to the Campine region, but politically and ecclesiastically was part of the Bishopric of Liège until 1569.

Because of its strategic position in the defence of the port of Antwerp, Brasschaat became an important military outpost during World War I.

The name was chosen in homage to the municipality of Brasschaat; the organisation's historical research project was initiated in this town in 1999.

The town hosts a couple of famous sports events, the biggest one being the yearly Premium European Cup triathlon.
