One of Arthur’s warriors in Welsh legend.

In Culhwch he was titled 'King of France' - probably representing William I - although the same distinction is given to Iona and Paris in the same stories. Attending at Arthur's court was also his son-in-law, Duke Alan Fyrgant.

As one of his tasks, the warrior Culhwch had to obtain Gwilenhin’s help in hunting the boar Twrch Trwyth. Gwilenhin did attend the hunt, and was killed by the boar at Aber Tywi.
