Wikipedia says
A superhero or superheroine is a stock character that typically possesses superpowers, abilities beyond those of ordinary people, and fits the role of the hero, typically using their powers to help the world become a better place, or dedicating themselves to protecting the public and fighting crime.
So yes, he is definitely dedicated to protecting the public, but it feels wrong to call him a super hero. What do you think?
Uncle Owen literally calls Obi-Wan a wizard — “That wizard’s a crazy old man” — so canonically that is how Jedi are seen by (at least some of) the population.
Oh. I didn’t know that. I’m more of a Star Trek guy.
