I will review the recent lattice results concerning the Nucleon structure obtained in the framework of the European Twisted Mass Collaboration (ETMC). We have computed the Nucleon Generalized Form Factors using nf=2 twisted mass fermions with pion masses up to 280 MeV and several lattice spacing in the range [0.05, 0.1] fm. Our results include elastic electomagnetic and axial form factors, as well as the first moments of PDF and GPD. Together with with the results of other lattice collaborations, they show that some simple Nucleon observables are still in severe disagreement with experimental data.
