The Congress of the Republic (Spanish: Congreso de la República) is the unicameral legislature of the Republic of Guatemala. The Guatemalan Congress is made up of 158 deputies who are elected by direct universal suffrage to serve four-year terms. The electoral system is closed party list proportional representation. 31 of the deputies are elected on a nationwide list, whilst the remaining 127 deputies are elected in 22 multi-member constituencies. Each of Guatemalas's 22 departments serves as a district, with the exception of the department of Guatemala containing the capital, which on account of its size is divided into two (distrito central and distrito Guatemala). Departments are allocated seats based on their population size and they are shown in the table below.
