The present invention relates to an apparatus and a method for power control for V2X communication. The apparatus includes a reception message analyzing unit for analyzing headers of reception messages received from communication devices of roadside apparatuses and surrounding vehicles located around a vehicle; a message loss checking unit for checking whether or not loss of the reception messages occurs by counting sequential numbers included in the headers of the reception messages; a density analyzing unit for analyzing a density for each of communication devices located in a communication radius of preset transmission power from the vehicle when the message loss checking unit determines that the loss of the reception message occurs; and a transmission power determining unit for determining transmission power for V2X communication by deducting the preset transmission power in units of reference power according to the density when the density around the vehicle exceeds a reference value.
