Knock-knock jokes are the one joke format that never really goes out of style — there’s something about the back-and-forth that makes even the corniest pun land. Halloween just gives the format a built-in reason to exist: what better excuse to knock on someone’s door than trick-or-treating? Below are 60 knock-knock jokes split into two sections — one for kids, one with a little more wit for teens and adults — so there’s something for the whole porch line.
For more Halloween humor by age and style, check out the full Halloween jokes collection, or browse Halloween jokes for kids, Halloween jokes for toddlers, and Halloween jokes for adults.
How to Tell a Knock-Knock Joke (The Right Way)
The format only works with the full back-and-forth — don’t skip a line, even if it feels obvious:
You: Knock knock. Them: Who’s there? You: [Setup word] Them: [Setup word] who? You: [Punchline]
Say it with a pause before the punchline — that half-second of anticipation is half the joke.
