The recent discovery at the LHC of a particle compatible with the Higgs boson may open a window on scenarios of new physics beyond the Standard model. In fact, searches for new heavy fermionic states have been undertaken both at Tevatron at the LHC , but no evidence have emerged so far, pushing the mass bounds above 400-600 GeV, depending on specific scenarios. Vector-like quarks are however predicted in various scenarios of new physics, and their peculiar signatures are worth investigating in detail. I will illustrate the phenomenology of vector-like quarks from a point of view which is as model independent as possible, describing a minimal scenario with the inclusion of a new vector-like state which couples to SM quarks through Yukawa interactions. Constraints coming from modifications of SM observables will also be analysed and some of the most promising signatures of vector-like quarks at the LHC will be presented.
