We consider directed polymers in random environment in the critical dimension, focusing on the intermediate disorder regime when the model undergoes a phase transition. We prove that, at criticality, the diffusively rescaled random field of partition functions has aunique scaling limit: a universal process of random measures onwith logarithmic correlations, which we call theCritical 2d Stochastic Heat Flow. It is the natural candidate for the long sought solution of the critical 2d Stochastic Heat Equation with multiplicative space-time white noise.
