The existing evidence is reviewed, and new 21-cm H I data are presented, concerning the shape of the rotation curve both in the inner and the outer parts of M31. It is concluded that a substantially constant value for the mass-to- luminosity ratio as a function of radius both for the spheroidal and the exponential disk components of the distribution of luminosity is in good agreement with the observations.
