Tamarin is a city located in Nicaragua. It serves as a geographical location within the country's regional landscape.
While the name "Tamarin" is associated with a specific municipality, it is also shared by a genus of squirrel-sized New World monkeys from the family Callitrichidae. These primates are characterized as the first offshoot in the Callitrichidae tree and are considered the sister group to a clade that includes lion tamarins, Goeldi's monkeys, and marmosets.
