The Congress of the Republic (Spanish: Congreso de la República) is the unicameral body which exercises legislative power in Peru. Due to the broadly interpreted impeachment wording in the Constitution of Peru, the President of Peru can be removed by Congress without cause, effectively making the legislature more powerful than the executive branch. Following a ruling in February 2023 by the Constitutional Court of Peru, the body tasked with interpreting the Constitution of Peru and whose members are directly chosen by Congress, judicial oversight of the legislative body was also removed by the court, essentially giving Congress absolute control of Peru's government. Since the 2021 Peruvian general election, right wing parties have held a majority in the legislature. The largest represented leftist party in Congress, Free Peru, has subsequently aligned itself with conservative and Fujimorists parties within Congress due to their institutional power.
Congress's composition is established by Chapter I of Title IV of the Constitution of Peru. Congress is composed of representatives who sit in congressional districts allocated to each region, as well as two special districts, Lima Province and Peruvian citizens living abroad, on a basis of population as measured by the Peruvian Census in multi-member districts. The number of voting representatives is fixed by the Constitution at 130. Pursuant to the 2017 Census, the largest delegation is that of Lima Province, with 36 representatives.
