To consolidate the other two responses:
There are two things already implemented, register_uninstall_hook() and uninstall.php.
The first hook registers code to run when a plugin is deleted (not deactivated) through the plugins page GUI.
Second, if your plugin directory contains an uninstall.php file, it will be loaded when your plugin is deleted.
Two different ways of doing the same thing, basically.
Some plugins do (incorrectly, IMO) remove their own data when deactivated, but this is not official best practice.
