Transferring instant messaging sessions includes receiving a selection, from a user within a user interface, of at least one instant messaging session from among multiple instant messaging sessions to transfer from a first instant messaging controller on a first device to at least a second instant messaging controller on a second device, where the user is signed on concurrently to the first instant messaging controller on the first device and the second instant messaging controller on the second device. At least a portion of the selected instant messaging session is transferred from the first instant messaging controller on the first device to the second instant messaging controller on the second device and the transferred portion of the instant messaging session is made perceivable on the second instant messaging controller on the second device.
