High accuracy radial velocities have been obtained for 404 F and M supergiant stars belonging to the LMC using the photoelectric scanner CORAVEL. The observations are presented and the determination of the accuracy is described. The results are compared to the previous work of Feast et al. (1960), Ardeberg et al. (1972), and Brunet et al. (1973), and a new determination of the average velocity dispersion in the LMC is given. The general trend of the stellar velocities, as compared to the radial velocities of gaseous components, is examined. A systematic shift of about 6 km/s between velocities of KM and OBA stars is observed, while agreement is excellent with H I velocities. The surface distribution of radial velocities shows a tendency of stars to cluster in groups with low intrinsic velocity dispersions. A preliminary mean velocity dispersion of 5.3 km/s is determined for KM stars.
