Morinje (Morinjski zaljev, Italian: Morigne, Lago di Castello Andreis) is the toponym for a bay in Croatia.

The Morinje Bay in Dalmatia, with a surface area of 3.5 km² and a maximum depth of 21 metres, is situated five kilometres south-east of Šibenik in the central part of the eastern Adriatic coast.

It is hydrogeomorphologically divided into two parts – a shallow northern funnel (Morinje) and the deeper southern channel-shaped Jadrtovac passage.

[1] Morinje has no permanent riverine inflow, only an insignificant and intermittent superficial rivulet (Ribnik) and several underwater springs.

In modern times, economic activities in the area are primarily associated with agriculture and seasonal tourism.
