Llawfrodedd Farfog or Llawfrodedd Farchog (Middle Welsh) is a hero of Welsh tradition. The meaning of the personal name "Llawfrodedd" is uncertain, however, it is suggested that the name is associated with Llawfrydedd 'Sorrow', the epithets "Farfog" ("barfog") and "Farchog" ("marchog") mean "bearded" and "horseman" respectively.
Llawfrodedd is a hero of Arthur's court in the tales of "Culhwch and Olwen" and "Breuddwyd Rhonabwy". Several examples of the word 'Llawfrodedd' are found in the work of the medieval "Gogynfeirdd" poets, but it is not clear if it occurs as a proper name.
The evidence suggests that Llawfrodedd may have been one of 'Men of the North', but this can not be proven.
