This is a survey paper on derived symplectic geometry, that will appear as a chapter contribution to the book "New Spaces for Mathematics and Physics", edited by Mathieu Anel and Gabriel Catren. Our goal is to explain how derived stacks can be useful for ordinary symplectic geometry, with an emphasis on examples coming from classical topological field theories. More precisely, we use classical Chern-Simons theory and moduli spaces of flat G-bundles and G-local systems as leading examples in our

In the main body of the Chapter we try to convince the reader how derived symplectic geometry (after Pantev-Toën-Vaquié-Vezzosi somehow reconciles all these different point-of-views.
