Pope John Paul II is not officially a patron saint. While he is a saint in the Catholic Church, he hasn't been designated as the patron saint of any particular group, place, or activity. Patron saints are typically chosen based on their lives, miracles, or connection to a specific cause.
However, it's not uncommon for people to unofficially consider a saint as a patron for something they feel a personal connection to. So, while there's no official designation, some individuals or groups might feel a particular affinity for St. John Paul II and consider him a patron in their own way.
