Acre ([ˈakɾi] (About this soundlisten))[3] is a state located in the northern region of Brazil. Located in the westernmost part of the country with a two hour time difference from Brasília, Acre is bordered clockwise by the Brazilian states of Amazonas to the north and northeast, Rondônia to the east, the Bolivian department of Pando to the southeast, and the Peruvian regions of Madre de Dios, Ucayali and Loreto to the south and west. It occupies an area of 152,581.4 km2.

Its capital and largest city is Rio Branco. Other important places include Cruzeiro do Sul, Sena Madureira, Tarauacá and Feijó.

Intense extractive activity, which reached its height in the 20th century, attracted Brazilians from many regions to the state. From the mixture of sulista, southeastern Brazil, nordestino, and indigenous traditions arose a diverse cuisine, which unites sun-dried meat (carne-de-sol) with pirarucu, a typical fish of the region. Such dishes are seasoned with tucupi, a sauce made from manioc.

Fluvial transport, concentrated on the Juruá and Moa rivers, in the western part of the state, and the Tarauacá and Envira Rivers in the northwest, is the principal form of transportation, especially between November and June, when rain leaves impassable the BR-364, which connects Rio Branco to Cruzeiro do Sul.
