HNLMS De Zeven Provinciën was a Royal Netherlands Navy coastal defence ship in service from 1910 until 1942. It was a small cruiser-sized warship that sacrificed speed and range for armor and armament. She was armed with two 283 mm, four 150 mm, ten 75 mm, four 37 mm guns, in addition to a few 75 mm mortars. She was 101.5 metres (333 ft) long, had a beam of 17.1 metres (56 ft) and a draft of 6.15 metres (20.2 ft), and displaced 6,530 tons. She had a crew of 448 and was able to reach 16 knots.

Coastal defence ships were warships built for the purpose of coastal defence, mostly during the period from 1860 to 1920. They were small, often cruiser-sized warships that sacrificed speed and range for armour and armament. They were usually attractive to nations that either could not afford full-sized battleships or could be satisfied by specially designed shallow-draft vessels capable of littoral operations close to their own shores. The Nordic countries and Thailand found them particularly appropriate for their island-dotted coastal waters. Some vessels had limited blue-water capabilities; others operated in rivers.
