  Lecture notes of a course on birational geometry (taught at College de
France, Winter 2011, with the support of Fondation Sciences Math\'ematiques de
Paris). Topics covered: introduction into the subject, contractions and
extremal rays, pairs and singularities, Kodaira dimension, minimal model
program, cone and contraction, vanishing, base point freeness, flips and local
finite generation, pl flips and extension theorems, existence of minimal models
and Mori fibre spaces, global finite generation, etc.
