Nybroviken (Swedish for "New Bridge Bay") is a bay in central Stockholm, Sweden. . Nybroviken separates the city district Östermalm from the peninsula Blasieholmen. North of the bay is Berzelii Park and Norrmalmstorg. To the south Nybroviken connects to the bay Ladugårdslandsviken. Facing both these bays are the quays of Strandvägen and Nybrokajen. The name stems from the historical bridge Ladugårdslandsbron ("Barn's Land's Bridge"), also known as Nybro, which once stretched across the bay to connect to Nybrogatan.
