Disclosed are a method for transmitting and receiving multicast/broadcast data in a wireless communication system, and an apparatus therefore. Specifically, a method by which a station transmits a reference signal for demodulating multicast/broadcast data in a wireless communication system comprises the steps of: mapping a first reference signal within a control channel region consisting of at least one symbol used for transmission of a control channel within a subframe; and mapping a second reference signal transmitted from multiple cells for demodulating a multicast/broadcast channel within a data channel region excluding the control channel region within at least one resource block which has been allocated for transmission of the multicast/broadcast channel which carries the multicast/broadcast data transmitted from the multiple cells within the subframe, wherein scheduling information for allocating at least one resource block where the multicast/broadcast channel is mapped may be transmitted in the control channel.
