An induction ring is one of seven types of hypothetical space drives suggested by Marc Millis of the Breakthrough Propulsion Physics Program at NASA's Glenn Research Center (see Millis drives).

An induction ring of negative energy – analogous to negative numbers – would warp space into a sort of bubble around the spacecraft. This would be similar to the effect created by the bias drive.

Compare with Alcubierre warp drive.
