Santa Maria is a medieval church in the comune of Uta, Sardinia, Italy.
The exact date of construction is unknown, although it is generally assigned to the mid-12th century by monks from the Abbey of St. Victor in Marseille, perhaps on the ruins of a pre-existing structure. It is an example of Provençal and Tuscan Romanesque styles' influence on the local medieval architecture (at the time the area was under the influence of the Republic of Pisa).
The oldest known mention of the church is in a 1363 document, by which king Peter IV of Aragon switched it from the Knights Hospitaller to the Order of Sant Jordi d'Alfama. The edifice was later held by the Franciscans, who, in the late 16th century, gave it to the archdiocese of Cagliari.
