We present a search for a dark photon (A'), a new light gauge boson introduced by dark sector models, using data collected by the BABAR experiment. The dark photon is identified through its decay into a lepton pair in the reaction e+e- -> gamma A', A' -> l+l- (l=e,mu). We observe no statistically significant signal, and we set 90% confidence level upper limits on the mixing strength between the photon and dark photon at the level of 10-3 - 10-4 for dark photon masses in the range 0.02 - 10.2 GeV.
