The ALICE experiment is dedicated to the study of heavy-ion collisions at LHC energies. ALICE has a high-quality hadron identification system in the central region e.g. a Inner Tracking System, a large Time-Projection-Chamber, a Time-Of-Flight and the High Momentum Particle Identification Detector (HMPID). The ALICE HMPID detector has been designed to identify charged hadrons ({rho}, K, p) in the momentum range 1<p<5 GeV/c. Despite its limited geometrical acceptance, less than 10% of the central ALICE barrel, the HMPID detector has successfully accumulated enough statistics during the first proton-proton runs at LHC, to allow the detector alignment and to evaluate the calibration parameters needed to estimate its performance. Preliminary HMPID results from p-p collisions at {radical}(s) = 7 TeV and its future contribution to the ALICE physics programme, will be presented.
