The Cachoeira da Fumaça ("Smoke Falls", also known as "Glass Falls") is 340 m tall waterfall in Bahia, Brazil. It was believed to be the country's highest waterfall until the 353 m tall Cachoeira do Araca (Cachoeira do El Dorado) was recently discovered in the state of Amazonas.

Cachoeira da Fumaça is located in Palmeiras, Bahia, Chapada Diamantina, an attractive region for adventurers, named that way because the tiny water flow is sprayed by the wind before it touches the ground. However, depending on the season, it can be completely dry.

There are two ways to reach it: from above, walking 6 kilometers (3.7 mi) from the ecological base placed in the Vale do Capão, or from below, after a three-day trek starting from Lençóis, Chapada's best-known city.

Local people knew about the waterfall but wider public learned about it after it was noticed by bush pilot George Glass in 1960.
