The present disclosure relates to a receiving device and a receiving method that can receive both signals of a GNSS signal and a wireless LAN at lower cost and more compactly. A selecting unit selects either a received GNSS signal or wireless LAN signal. By multiplying the signal selected in the selecting unit by a local oscillation signal generated in a local oscillation circuit, a converting unit converts the selected signal into an IF signal with lower intermediate frequency. A control unit controls the selecting unit, and performs control so that the GNSS signal and the wireless LAN signal are processed in a time-sharing manner in the converting unit. The technology of the present disclosure can be applied to a receiving device that receives a signal from a GPS satellite, for example.
