The Chamber of Deputies, officially the Honorable Chamber of Deputies of the Argentine Nation, is the lower house of the Argentine National Congress. It is made up of 257 national deputies who are elected in multi-member constituencies corresponding with the territories of the 23 provinces of Argentina by party list proportional representation. Elections to the Chamber are held every two years, so that half of its members are up in each election, making it a rare example of staggered elections used in a lower house.
