Cascatinha Taunay is a 35-meter waterfall located within Tijuca National Park in Rio de Janeiro, making it the tallest cascade in the park. It sits near Alto da Boa Vista and is fed by the convergence of the Rio Tijuca, the Rio Conde, and other tributaries.

The falls are surrounded by dense Atlantic Forest and a natural pool forms at their base.

The waterfall takes its name from French artist Nicolas-Antoine Taunay, who arrived in Rio de Janeiro with the French Artistic Mission in 1816, built a small house near the cascade in 1817, and immortalized it in his paintings.

A stone bridge shaped like a Roman arch, constructed in 1860 by engineer Job de Alcântara on commission from the Imperial Government, stands in front of the falls and adds a historic character to the site.

Access is straightforward, requiring no strenuous hike, and the park is free to enter. An open area near the waterfall is suitable for picnicking.
