Is point of view hyphenated?

It depends on the context. If you are simply referring to a person's perspective, "point of view" is correct.

On the other hand, if you're referring to the literary term, "point-of-view" is more accurate. In the literary sense, point-of-view refers to the perspective from which a story is written (e.g. first person, third-person, etc.), and is thus hyphenated to enclose the term.

All that being said, few people would bat an eyelash, whatever way you chose to write it.
