We present a simple exact formula for three-point velocity correlation functions in two-dimensional turbulence which is valid at all scales and which interpolates between the direct and inverse cascade regimes. As expected, these correlation functions are universal in these extreme regimes. We also discuss the effects of anisotropy and friction.
