Rombaken (Norwegian) or Ruoppat (Northern Sami)[1] (or unofficially: Rombaksfjord) is a fjord that branches off of the main Ofotfjorden in Narvik Municipality in Nordland county, Norway.

It is also where ORP Grom, one of the two most heavily armed and fastest destroyers of World War II, was sunk by a Heinkel He 11 from Luftwaffe's Kampfgeschwader 100.

Parts of the bow of the German destroyer Georg Thiele remain visible above the water in Rombaksbotn to this day.

The wrecks at Narvik remain popular diving spots, although some are off-limits because they still contain unexploded ordnance.

[4] The destroyers Anton Schmitt, Diether von Roeder and Wilhelm Heidkamp rest in 12 m (39 ft) of water there and were opened for diving.
