The tayra (Eira barbara), is an omnivorous animal from the weasel family, native to the Americas. It is the only species in the genus Eira.

Tayras are also known as the tolomuco or perico ligero in Central America, motete in Honduras, irara in Brazil, san hol or viejo de monte in the Yucatan Peninsula, and high-woods dog (or historically chien bois) in Trinidad. The genus name Eira is derived from the indigenous name of the animal in Bolivia and Peru, while barbara means "strange" or "foreign".
