Yes. Baboons are 'Old World' monkeys, a class of primates found
in a range of environments across Africa, North and East Asia, the
Middle East, Gibralta, and the southernmost reaches of Spain,
encompassing eighty or more species of primate.
Unlike apes, Old World monkeys possess tails. Their tails are
not prehensile, unlike New World Monkeys, who are capable of using
their tail effectively as an extra limb.
Baboons belong to the subfamily of Old World monkeys called
Cercopithecines, the other subfamily being Colobinae. Other
examples of Cercopithecines include Mandrills and Macaques, while
typical examples of Colobinae include the Colobus and Proboscis
monkeys.
Baboons are the largest of the old world monkeys.
