The object of this thesis is to investigate discrete subgroups of$PU(2,1)$, the group of holomorphic isometries of complex hyperbolic space of (complex) dimension 2. We are mostly concerned with those groups generated by elliptic motions, i.e. motions fixing a point of this space.The two guiding principles of this work are on one hand the use ofLagrangian subspaces (or real planes) and their associated reflections (antiholomorphic involutions), and on the other hand the study and understanding of the examples of lattices in $PU(2,1)$ which Mostow constructed in 1980.L'objet de cette thèse est l'étude de sous-groupes discrets de$PU(2,1)$, groupe des isométries holomorphes de l'espace hyperbolique complexe de dimension (complexe) 2.
