Yes, who is a pronoun.

What kind of pronoun is “who”?

“Who” is used in two main ways:

  • As an interrogative pronoun (to ask questions):
    • “Who is calling?”
    • “Who did this?”
  • As a relative pronoun (to introduce a clause about a person):
    • “The student who arrived late sat at the back.”
    • “She’s the doctor who treated me.”

In both cases, “who” stands in for a noun that refers to a person or people, so it counts as a pronoun.

Grammar details (quick)

  • “Who” is usually a subject pronoun, like “I, he, she, we, they.”
* “Who won the game?” → “Who” = the one doing the action.
  • Related forms:
    • “Whom” (object form): “Whom did you see?”
* “Whose” (possessive): “Whose bag is this?”

So if you’re wondering “is who a pronoun?” the clear answer is: yes, it’s an interrogative and relative pronoun used for people.
