A radio-frequency switch includes a first switch circuit including a first common terminal, at least two first selection terminals, a first switch that selectively connects the first common terminal and the at least two first selection terminals to each other, and a first shunt switch that switches the first common terminal and ground between a conductive state and a non-conductive state with each other, and a second switch circuit including a second common terminal that is connected to the first common terminal, at least two second selection terminals, and a second switch that selectively connects the second common terminal and the at least two selection terminals to each other.
