Taxonomy defines several classes which a species falls into. These are: Kingdom, Phylum, Class, Order, Family, Genus, and finally Species.
As you specify only "Monkey", what species name is impossible to determine. Monkeys are of the Primate order though, and monkeys (not apes, however) are of the families Cercopithecoidea or Platyrrhini. Apes, which are closer to humans, are in the family Hominoidea.
