Casa Cosmana Navarra (English: Cosmana Navarra House) is a 17th-century aristocratic townhouse in Rabat, Malta. The building belonged to Cosmana Navarra (1600-1687), for whom it is named until date, who was the main benefactress of the rebuilding of the Rabat parish church of St. Paul. The house is found in front of the parish church opposite the Wignacourt Museum. Most of the building was converted into a restaurant, namely the Ristorante Cosmana Navarra.
