List of longest prison sentences served

This is a list of longest prison sentences served by a single person, worldwide, without a period of freedom followed by a second conviction. These cases rarely coincide with the longest prison sentences given, because some countries have laws that do not allow sentences without parole or for convicts to remain in prison beyond a given number of years (regardless of their original conviction).
