The present invention relates to a method for receiving a synchronisation reference signal for device-to-device (D2D) communication by a first terminal in a wireless communication system and an apparatus therefor. More specifically, the present invention comprises a step of receiving a plurality of synchronisation reference signals including a first synchronisation reference signal and a second synchronisation reference signal over a D2D synchronisation reference signal transmission cycle, wherein the first synchronisation reference signal is transmitted by a cluster head for D2D communication and the second synchronisation reference signal is transmitted by a second terminal that belongs to a cluster for the D2D communication.
