The Griffith surname is of Welsh origin, derived from the ancient Welsh personal name 'Gruffudd'. Gruffudd is a combination of the elements 'griff', meaning 'strong' or 'fierce', and 'udd' meaning 'lord or 'prince'. Thus, the Griffith surname carries the meaning of 'Strong Lord' or 'Fierce Prince'.
The surname, like most Welsh ones, became popular through patronymic learning conventions. It was a popular personal name, especially amongst princes, such as the infamous Griffith ap Cynan, a Prince of North Wales.
In Wales, the Griffith surname is most commonly found in Gwynedd, in Northwestern Wales. This is the original home of several princes and kings named Griffith/Gruffudd.
