People who live in or are from Paris, France.
From Paris (the city, named after the Parisii Celtic tribe) + '-ian' suffix meaning 'from' or 'of.' The Parisii were the Gallic tribe that originally settled there.
Parisians have a reputation for speaking only French and being unfriendly to tourists, but research shows they're actually quite helpful if you greet them in French first—it's about cultural respect, not rudeness.
