Ranking dos Políticos is an independent Brazilian organization that promotes transparency and public oversight of the National Congress. Established in 2011, it researches and analyzes parliamentarians’ performance, aiming to encourage good public management, strengthen democracy, and bring citizens closer to the work of their representatives. The organization states that it has no ties to political parties, politicians, or interest groups and bases its evaluations on the public interest.

Its main service is a ranking that monitors federal deputies and senators using official information from Congress, including voting records, office expenses, and legal proceedings. A scoring system assigns positive or negative points according to criteria defined by its Legislative Council, then combines the results into clear comparisons. Visitors can filter parliamentarians by chamber, party, state, and year, review score breakdowns, compare representatives, and follow congressional votes.

Ranking dos Políticos also publishes studies, technical notes, parliamentary bulletins, surveys, articles, and election-related analysis.
