We introduce the new concept of silting modules. These modu les generalise tilting modules over an arbitrary ring, as well as support τ-tilting modules over a finite dimensional algebra recently introduced by Adachi, Iyama and Reiten. We show that silting modules generate tors ion classes that provide left approximations, and that ever y partial silting module admits an analogue of the Bongartz co mplement. Furthermore, we prove that silting modules are in bijection with 2-term silting complexes and with certain tstructures and co-t-structures in the derived module categ ory. We also see how some of these bijections hold for silting comp lexes of arbitrary finite length.
