Which one is correct who doesn't or who don't?

Answer 1

Who doesn't is typically the correct form. That is because "doesn't" is a contraction of the two words "does" and "not" which would make the phrase "Who does not." The phrase "who don't" is incorrect because "don't" is a contraction of the words "do" and "not," which is therefore wrong because in the English language, the subject "who" (a pronoun) "does" things. (Example: "Who doesn't love Baseball?" and "Who does not love baseball?" instead of "Who don't love baseball?" and "Who do not love baseball?")

Who don't (a contraction of do not)can also be grammatically correct, used in the middle of a sentence. Example:

"Hot Dogs are available, for those who don't like Hamburgers."

Answer 2

"Who doesn't" is correct. Use it when referring to a singular subject, for example "He is the one who doesn't like chocolate." Use "who don't" when referring to multiple subjects, like "They are the ones who don't eat meat."
