The Suburbicarian Diocese of Palestrina () is a Latin suburbicarian diocese centered on the comune of Palestrina in Italy.

The current bishop of Palestrina is Mauro Parmeggiani, who was appointed by Pope Francis on 19 February 2019. Prior to his appointment, he had served as Apostolic Administrator following the resignation of his predecessor, Bishop Emeritus Domenico Sigalini, on 31 July 2017 due to age.

History

In 1060, the Diocese of Gabii was suppressed and its territory was incorporated into the Diocese of Palestrina. During the conflict between Pope Boniface VIII and the Colonna family, Palestrina was destroyed by papal order in 1299. Boniface established a new settlement, known as ''Civitas Papalis'', on the plain below the former city and transferred the episcopal and cardinalitial title there. The new settlement was short-lived, and the traditional title of Palestrina was restored in 1306. Palestrina was looted in 1473.Ferdinand Gregorovius, A History of the City of Rome in the Middle Ages Volume VII. part 1 (London: Bell 1900), pp. 57–60.

During the 17th century, the comune of Palestrina was the family territory of a number of Italian noble families including the Barberini, Colonna and d'Este families (which regularly intermarried). Members of these families are represented throughout the list of diocese Bishops, especially between 1600 and 1800. Barberini Pope Urban VIII appointed a number of relatives and close supporters to the Palestrina diocese and governmental positions.

Palestrina is one of the six suburbicarian dioceses of Rome, each traditionally assigned to a cardinal as titular bishop. Although this is a high-ranking position—one of only six in the Order of Cardinal BishopsUmberto Benigni, "Diocese of Palestrina", Retrieved: 2016-10-19. —since 1972, the title has been purely honorary. The governance of the diocese is now entrusted to a residential bishop, as ordained in the Motu Proprio "Suburbicariis Sedibus" and the cardinal bishop no longer exercises actual authority over its administration.

Bruno 1059–1060 Bernhard 1061–1065 Loperto 1066–1069 vacant 1069–1073 Uberto Belmonte 1073–1082 [Berardo (?) ca.1092 (?)]Hüls, p. 111 no. 8 says that Bernardo's existence is dubious because he appears only in one bull dated September 1092 which has been recognized as a forgery, though possibly based on original documents. Klewitz, p. 117 does not mention him among the occupants of this suburbicarian see. Ugone Candido 1089–1099 (pseudocardinal) Milone 1095/98–1104 vacant 1104–1107Some sources mention cardinal Corrado 1105–1106 but the only document attesting his existence (bull of Paschalis II in favour of the church of S. Salvatore dated 27 December 1105) has been recognized as falsehood and both Klewitz, p. 120 and Hüls, p. 112–113, eliminated him from the list of the bishops of Palestrina Cuno of Praeneste 1107–1122 Guillaume Praenestinus 1123–1137Source for the period 1130–1187: Brixius p. 135 Johannes 1130–1134 (pseudocardinal) Étienne de Châlons 1139–1144 Guarino Foscari 1144–1158 Giulio I 1158–1164 vacant 1164–1176Some sources mention cardinal Ugo or Ottone occupying that see ca. 1164 but Brixius, pp. 60–68 excludes him from the list of cardinals created by Alexander III because no papal bulls signed by him has been found. Probably he is confused with cardinal-bishop Odo of Tusculum 1170–1171 (cf. Brixius, p. 65 no. 21) Vibiano 1168–1173 (pseudocardinal) Manfredo de Lavagna 1176–1178 vacant 1178–1179 Benerede 1179–1180 Paolo Scolari 1180–1187 vacant 1188–1191Source for the period 1188–1228: Maleczek, p. 63 Giovanni III da Anagni 1190–1196Some sources indicate that abbot Mainard of Pontigny became bishop of Palestrina in 1188 and died few weeks after his promotion but Maleczek, p. 125 says that Mainard is attested as abbot of Pontigny until 1192. Therefore, he should be excluded from the list of the bishops of Palestrina vacant 1196–1200 Guy de Paré, O.Cist. 1200–1204Guy de Paré was born at Paray-le-Monial, diocese of Autun.
