The LifeDrive was a Palm OS-based handheld personal digital assistant device that was produced by PalmOne, a former incarnation of Palm, Inc. The device was PalmOne's first and only foray into the "Mobile Manager" device category. As its name suggests, Palm intended the LifeDrive to be capable of providing all the capabilities and data storage space that a user could possibly need during the course of the day, including contacts, calendar, music, images, video, and applications. At the time of release, the 4-gigabyte capacity that was chosen for this task could not be achieved using the flash memory used by most PDAs, while keeping the cost of the device low enough for consumer purchase.

The LifeDrive featured Bluetooth and Wi-Fi connectivity, the first Palm handheld to feature both. The device came pre-loaded with eReader, Documents To Go, and WiFile software.
