Are tamarins classified as apes or monkeys within the primate order?

Answer

Monkeys

Tamarins are unequivocally classified as monkeys. This places them within the Haplorhines group, specifically diverging from apes, which belong to a separate lineage. Tamarins fall into the infraorder Platyrrhini, recognized as New World monkeys. Apes, conversely, are catarrhines originating from Africa and Asia, and are structurally distinct, notably lacking tails, unlike monkeys.
