Abstract: Gauge theories describe fundamental interactions in nature but are hard to solve especially in strongly coupled regime. On the other hand, integrable models which usually appear in low dimensional many-body systems preserve infinitely many conserved charges and can be solved exactly. It is realized in recent years that certain large N gauge theories in 4 dimensions can be seen as an integrable system which raises the hope to solve them exactly. In this talk, I will give an overview of the beautiful relation between large N gauge theory and integrability. In particular, I will explain in detail how to compute correlation functions of local gauge invariant operators of the planar $\mathcal{N}=4$ Super-Yang-Mills theory using integrability. I will also comment on the computation of other interesting quantities such as Wilson loops and scattering amplitudes and generalizations to other theories.
