The name “Marlon” could refer to many different people, so the answer depends on which Marlon is meant.

If the question is about Marlon Brando, he was from Omaha, Nebraska, in the United States. If it is about Marlon Wayans, he was born and raised in New York City, also in the United States. If you meant the TikTok creator and basketball player Marlon Lundgren Garcia (often associated with streamers), he is from Malmö, Sweden.
