Clube de Regatas do Flamengo, universally known as Flamengo, is a powerhouse Brazilian multi-sports club established in Rio de Janeiro on November 17, 1895, initially as a rowing club. It quickly became renowned for its professional football team, which is the most popular in Brazil with over 46.9 million fans, and one of only two clubs never relegated from the top division.

Flamengo is not only Brazil's richest and most valuable football club but also recognized as the most successful Brazilian team of the 21st century so far, boasting an immense social media following. Its acclaimed 'Ninho do Urubu' youth academy has famously produced a wealth of talent, including football legends like Zico, Vinícius Júnior, and Lucas Paquetá. Flamengo players have also significantly impacted the Brazil national team, with Leônidas da Silva earning the Golden Boot and Ball in the 1938 World Cup and Zizinho the Golden Ball in 1950, among other contributions.
