In this review I will concentrate on three questions concerning the issue of dark matter in spiral galaxies. In the first place (and for the most part) I will discuss the analysis of rotation curves and the question whether the “maximum–disk hypothesis” is valid. Then I will discuss independent measurements of the disk mass distribution from the thickness of stellar and HI disks. Then follows a review of estimates of the flattening of the dark halos and a short discussion on the possible nature of the dark matter.
