In these notes we present a brief introduction to string theory. As a motivation we start by exposing some of the many striking achievements of the Standard model of fundamental interactions but also some of its limitations. We introduce string theory through a discussion of perturbative closed bosonic string. Since no knowledge of supersymmetry is assumed the different, consistent, superstrings are just qualitatively motivated. D-branes and open string are then discussed and some rough idea about dualities and non perturbative effects is advanced. We end by illustrating the idea of brane worlds as a possible framework to embed the Standard model in a string theory context.
