The Museu da Água (Water Museum) is located in Lisbon, Portugal.
The museum, the former steam pumping station of Barbadinhos, Lisbon, built in 1880, is in a 19th-century industrial building. The museum features four large steam engines dating from 1880. One has been reconditioned as a working demonstration. The pumps were in use until 1928. The museum also features portions of Lisbon's 1746 aqueduct.
In 1990 the museum was awarded the Council of Europe Museum Prize.
