As planets form and grow within gaseous protoplanetary disks, the mutual gravitational interaction between the disk and planet leads to the exchange of angular momentum, and migration of the planet. I review the current understanding of disk-planet interactions, focussing in particular on physical processes that determine the speed and direction of migration. The role of Lindblad and corotation torques as a function of the disk properties will be discussed, as well as the evolution of eccentricities and inclinations. Finally, I address the question of how well global models of planetary formation that include migration are able to match observations of extrasolar planets.
