Keuskupan Suburbikaris Ostia

Uskup Ostia adalah kepala keuskupan suburbikaris Ostia, salah satu dari tujuh tahta suburbikaris dari Roma. Posisinya sekarang diserahkan kepada jabatan Kepala Dewan Kardinal sejak 1150,The Cardinals of the Holy Roman Church - Guide to documents and events (76-2005) This statement of Miranda is unsourced. Moreover, Rudolf Hüls (pp.79-80) has demonstrated that the perpetual leadership of the Bishop of Ostia is not the case, but that the principle of seniority held true in Rome as it did elsewhere (cf. Hüls, pp. 77-78), before and after Pope Eugenius III. It was not until Pope Paul IV that the Deanship and the Bishopric of Ostia were tied together, in his Bull of 22 August 1555, Cum venerabiles.  dengan kepengurusan asli dari keuskupan tersebut diserahkan kepada Vikar Umum Roma.
