I discuss the holographic approach to the Langevin equation describing the motion of a heavy quark propagating through the deconfined Quark-Gluon Plasma (QGP). The Langevin diffusion coefficients are directly related to the jet quenching parameter, which enters in the reconstruction of RHIC events involving heavy probes. After a brief review of the Langevin equation, I discuss the calculation of the Langevin coefficients in 5-dimensional holographic duals. Finally, I discuss the results for the jet quenching parameter in a phenomenological holographic QCD model.
