Monserrato (Pauli or Paulli in Sardinian language) is a comune (municipality) in the Metropolitan City of Cagliari, southern Sardinia, Italy, located about 5 kilometres (3 mi) northeast of Cagliari.

Monserrato borders the following municipalities: Cagliari, Quartu Sant'Elena, Quartucciu, Selargius, Sestu.

In the Middle Ages, the village was known as Pauli (Sardinian language for marsh), and was part of the Giudicato of Cagliari.

Later owned by the Republic of Pisa, the House of Aragon and the Giudicato of Arborea, it was depopulated by plague in 1348.

Since 1995 [3] the town has been part of the newly instituted Cagliari metropolitan area.
