The Nabão (Portuguese pronunciation: [nɐˈbɐ̃w]) is a river in Portugal.
It rises in Ansião and passes through the city of Tomar before joining the Zêzere River — a course of about 66 kilometres (41 mi).
The swift waters of the Nabão once fed the factories of Tomar.
In 2013, development work in Tomar includes construction of road and foot bridges, promenades and gardens.
