Museu do Amanhã or The Museum of Tomorrow is a science museum in the city of Rio de Janeiro, Brazil. It was designed by Spanish neofuturistic architect Santiago Calatrava, and built next to the waterfront at Pier Maua.

The main exhibition takes visitors through five main areas: Cosmos, Earth, Anthropocene, Tomorrow, and Us via a number of experiments and experiences. This intricate yet captivating museum mixes science with an innovative design to focus on sustainable cities and an ecological world.

The museum was part of the city's port area renewal for the 2016 Summer Olympics.
