Observational constraints on the galactic potential and modelling aspects are reviewed. The following conclusions come out. The mass distribution generating the galactic gravitational potential should include a bulge to account for the innermost features of the rotation curve, an extensive massive corona responsible for a flat rotation at large radius, and a disc able to produce a rotation curve as given by Rohlfs and Kreitschmann (1988) and a vertical force law Kz as from Bienaymé et al. (1987). We still know very little about the potential more than 1500 pc above the galactic plane.
