Palmeiras vs Flamengo is the biggest interstate rivalry in Brazil, with both teams fighting for titles and Palmeiras becoming more vulnerable due to lack of replacements in their board of directors.

Flamengo's fiercest and longest-standing rivalries are with the other "Big Four" of Rio de Janeiro: Fluminense, Botafogo and Vasco da Gama; as well as interstate rivalries with Atletico MG and Palmeiras.
