We report on the photon drag effect of Bose-Einstein condensates. We develop a microscopic theory of this effect, which occurs in a general system containing Bose-Einstein-condensed particles, possessing an internal structure of quantum states. Analyzing the response of the system to an external electromagnetic field, we find that the drag results in a flux of particles constituting both the condensate and the excited states. We show that in the presence of the condensed phase, the response of the system acquires step-like behavior as a function of the electromagnetic field frequency with the elementary step determined by the internal energy structure of the particles.
