We study non-standard interactions (NSIs) at reactor neutrino experiments, and in particular, the mimicking effects on \theta_13. We present generic formulas for oscillation probabilities including NSIs from sources and detectors. Instructive mappings between the fundamental leptonic mixing parameters and the effective leptonic mixing parameters are established. In addition, NSI corrections to the mixing angles \theta_13 and \theta_12 are discussed in detail. Finally, we show that, even for a vanishing \theta_13, an oscillation phenomenon may still be observed in future short baseline reactor neutrino experiments, such as Double Chooz and Daya Bay, due to the existences of NSIs. If time allows, I will also try to make a more general introduction to NSIs.
