We consider superfluidity and quantum vorticity in rotating spacetimes. The
system is described by a complex scalar satisfying a nonlinear Klein-Gordon equation.
Rotation terms are identified and found to lead to the transfer of angular momentum of
the spacetime to the scalar field. The scalar field responds by rotating, physically behaving
as a superfluid, through the creation of quantized vortices. We demonstrate the vortex
nucleation through numerical simulation
