Th\'eor\`emes d'\'equidistribution pour les syst\`emes dynamiques   d'origine arithm\'etique
  This survey article is about algebraic dynamics. It is mainly concerned by the arithmetic equidistribution theorems featured by dynamical systems. The contents are: - heights - algebraic dynamics, conjectures - equidistribution theorem on the projective line (after Bilu and Baker). It was written for the sesion 2006 of \'Etats de la recherche, Syst\`emes dynamiques polynomiaux.
