Parque Radical, Olympic sports park in Deodoro, Brazil.

Parque Radical is the sports park in Deodoro, in western Rio de Janeiro, built for the 2016 Olympic Games. It holds a 400-metre BMX track with jumps and sharp bends on a 4,000 m² site, a mountain-bike course whose high point was the 124 m Morro do Jaques, and the Deodoro Olympic Whitewater Stadium, with a 250 m competition channel and a 200 m training channel fed by seven pumps.

The park was constructed as a venue for the 2016 Olympic Games and hosted international competitions in extreme sports. After the games, the facility was converted to provide the public with ongoing access to high-quality sports amenities.

The park draws sports enthusiasts and young people eager to try modern athletic techniques in a dedicated setting. Its facilities were designed to welcome both beginners and experienced athletes, making action sports accessible to different skill levels.

The whitewater stadium lies in the western Deodoro district, next to a military academy whose grounds held other Olympic events. The canoe slalom course has lighting and a canoe lift that carries kayaks back to the start. The BMX track, on land lent by the army, was returned to the army after the Games, while the canoe and mountain bike areas stayed open to the public.

During the 2016 opening ceremony, each athlete placed at least one seed in small tubes; 13,725 seeds of 207 native Mata Atlântica species were collected, the number matching participating countries plus the refugee team. Planting on about 6,000 m² at the foot of the Maciço da Pedra Branca began on 25 September 2019 and was completed on 10 December 2019, creating the Floresta dos Atletas.
