  We develop the effective theory of large-scale structure for non-Gaussian
initial conditions. The effective stress tensor in the dark matter equations of
motion contains new operators, which originate from the squeezed limit of the
primordial bispectrum. Parameterizing the squeezed limit by a scaling and an
angular dependence, captures large classes of primordial non-Gaussianity.
Within this parameterization, we classify the possible contributions to the
effective theory. We show explicitly how all terms consistent with the
symmetries arise from coarse graining the dark matter equations of motion and
its initial conditions. We also demonstrate that the system is closed under
renormalization and that the basis of correction terms is therefore complete.
The relevant corrections to the matter power spectrum and bispectrum are
computed numerically and their relative importance is discussed.
