Entanglement is an essential property of quantum systems that encodes non-local correlations with no classical counterpart. In recent years it has become clear that entanglement is key to several fundamental challenges in physics, such as classifying all phases of matter and building a quantum computer. In this talk, I will discuss how entanglement provides new insights into thermalization and chaos in many-body systems. In particular, I will discuss how the existence of basic thermodynamical concepts such as entropy and temperature is a consequence of highly entangled quantum states. I will also discuss the universal features of chaotic quantum states, and how the knowledge of just a single such state can allow one to understand properties of a system at all temperatures.
