Oranjeplaat is a shallow access point and dive site on 't Veerse Meer in the Dutch province of Zeeland, situated near the town of Arnemuiden. The site reaches a maximum depth of five meters, making it well suited to less experienced divers.

The area around a fairway buoy is thickly colonized by mussels, while the sandy bottom hosts oyster beds covered in red seaweed and clusters of orange and pink sea squirts. Crabs, gobies, shrimp, pipefish, and snails are all commonly encountered here.

Oranjeplaat can be reached as either a shore dive or a boat dive. Shore divers can park on the grass and enter the water directly opposite the fairway buoy.

Because the site lies along an active fairway, diving outside the main boating season is advisable, and free ascents should be avoided. Surfers may also be present in the area.
