Huck Griffin is Peter Griffin's great grandfather who appeared in "I Am Peter, Hear Me Roar". He traveled with a friend named N-Word Jim, who once became upset with Huck when Huck called Jim a certain name which was Jim's people's word, informing Huck that he had no right using the word. Jim and Huck reconciled when Huck said Jim's name right when he asked for an oar.

He is voiced by Seth MacFarlane.
