The World Cup is the biggest football tournament on the planet. It happens every four years. Brazil's national team plays in bright yellow shirts and is so famous that most people on Earth would recognise the kit. Their nickname is the 'Seleção' (which just means 'the Selection').
Brazil has produced some of the most famous footballers ever. Pelé scored over 1,000 goals in his career and is often called the greatest player of all time. Other Brazilian legends include Garrincha, Ronaldo, Ronaldinho, Marta (one of the best women's players in history) and Neymar.
Beach football is its own version of the game, played on sand with bare feet and no shoes. Brazilians are world champions at it. The sand makes the ball harder to control, which is part of why Brazilian players are famous for their tricky footwork on grass too.
The biggest stadium in Brazil is the Maracanã, in Rio de Janeiro. When it first opened it held nearly 200,000 fans - more than any stadium ever built. Brazilian fans are known for singing, dancing and drumming through every match, no matter what the score is.
