We demonstrate substantial cancellation of the differential light shift of a magnetic-field-insensitive microwave hyperfine (clock) transition in 87Rb atoms trapped in an optical lattice. Up to 95.5% of the differential light shift is cancelled while maintaining magnetic-field insensitivity. Our technique should have applications in quantum information and frequency metrology.
