Bölscheøya (English: Bölsche Island) is an island southwest of Negerpynten, the southeastern point of Edgeøya. It is part of Tusenøyane. The island was named in 1868 by the German geographer August Petermann (1822-78) after the German journalist Carl Bölsche, father of the German writer and zoologist Wilhelm Bölsche (1843-93).
