The shape of the Danguk Peninsula, marked in dark green.

The Danguk Peninsula (Classic Zhenian: 檀國半島, Modern Zhenian: 단국반도), commonly referred to as Danguk (Classic Zhenian: 檀國, Modern Zhenian: 단국) is a peninsula located in eastern Tarsis. It extends about 1,100 kilometers to the southeast from continental Tarsis, dividing the Gulf of Danguk and the East Zhenian Sea; hence, it is surrounded by the East Zhenian Sea and the Gulf of Danguk to the east and west respectively, with the Strait of Zhenia connecting the two bodies of water. The peninsula is entirely controlled by Zhenia, being regarded as the 'Zhenian heartland' by Zhenians.
