Tallán (or Tacllán, after the use of the taclla, a farming tool) was a conglomerate of ethnic groups with a common origin that settled in the plains of north-western Peru, an ethnos with a matriarchal system.

(Due to their possible kinship, the tumpis, who settled in the current Department of Tumbes, are widely considered one of these ethnic groups.)

In the beginning the Tallán lived in behetrias, which were simple settlements without a head or an organization, in which all its members were engaged in the same and unique activity, mainly agriculture and fishing.

Narihualá (17 km south of Piura) is considered the capital of the Tallán Nation and is the most important architectural evidence of a great monument, both in its size and the prominent platforms of two pyramids.

Huaca El Loro, near Chiclayo, Peru is a Tallán archaeological site, where a 1000-year-old mummy of a nobleman was discovered.
