King Friday is the king of the Neighborhood of Make-Believe, the husband of Queen Sarah Saturday, and the father of Prince Tuesday and Prince Wednesday. He originally appeared in puppet form in the original Mister Rogers' Neighborhood.

King Friday first appeared and spoke in "Daniel's Picnic," in which Daniel visited the castle to pick up Prince Wednesday and Miss Elaina for their picnic.

As his wife's name is Queen Sarah Saturday, and we can assume the two are married, his full name is likely to be 'King Friday Saturday'
