We present the first 2D hydrodynamical simulations of the GG Tau circumbinary disk including self-gravity. These simulations match on many points the physical properties deduced from observations. We show that self-gravity is probably very important for the dynamical evolution of the system. In particular, we find that self-gravity noticeably affects the structure of the disk, the accretion rate onto the central binary and the orbital evolution of the binary.
