Llallagua (in hispanicized spelling) or Llallawa (Aymara for a monstrous potato (like two potatoes) or animal, Quechua for the god of seed-time during the Inca period)[1][2] is a town in the Potosí Department in Bolivia.

Llallagua features a rare microclimate amidst the semi-arid tundras of Potosí and Oruro, due to its extreme elevation near 4000m.

Summers are cool and wet with daily highs rarely rising above 22 °C, while winters feature cooler days with much colder nights averaging −4 °C.

These low temperatures are a result of the extreme precipitation deficit during the winter months with the resulting aridity leading to an increased diurnal temperature variation.
