District 21 () is one of the 28 multi-member electoral districts of the Chamber of Deputies, the lower house of the National Congress, the national legislature of Chile. The district was created by the 2015 electoral reform and came into being at the following general election in 2017. It consists of the provinces of Arauco and BiobÃÂo, and the commune of Lota in the province of Concepción in the region of BiobÃÂo. The district currently elects five of the 155 members of the Chamber of Deputies using the open party-list proportional representation electoral system. At the 2021 general election the district had 542,026 registered electors.
District 21 was one of 28 electoral districts established by Ley Nð20.840 passed by the National Congress in January 2015. It consisted of the communes of Alto BiobÃÂo, Antuco, Arauco, Cañete, Contulmo, Curanilahue, Laja, Lebu, Los ÃÂlamos, Los ÃÂngeles, Lota, Mulchén, Nacimiento, Negrete, Quilaco, Quilleco, San Rosendo, Santa Bárbara, Tirúa and Tucapel in the region of BiobÃÂo. In September 2018 the province of ÃÂuble was promoted to region status. As a result, the communes of Cabrero and Yumbel, which were located in the province of BiobÃÂo but were in District 19, were transferred from District 19 to District 21.
District 21 currently elects five of the 155 members of the Chamber of Deputies using the open party-list proportional representation electoral system. Parties may form electoral pacts with each other to pool their votes and increase their chances of winning seats. However, the number of candidates nominated by an electoral pact may not exceed the maximum number of candidates that a single party may nominate. Seats are allocated using the D'Hondt method.
