The knowledge of parton distributions and of their associate uncertainties plays a crucial role in the full exploitation of the LHC physics potential. I will present the main features and some results of the NNPDF collaboration's global fit of Parton Distribution Functions (PDFs). The approach is based on the the idea of combining a Monte Carlo sampling of the probability measure in the space of PDFs with the use of neural network as universal unbiased interpolating functions. I will show that the method produces interesting results and it is able to overcome some drawbacks of the traditional approaches.
