This is a list of the hypati, patricians, consuls, and dukes of Gaeta. Many of the dates are uncertain and sometimes the status of the rulership, with co-rulers and suzerain–vassal relations, is vague.

Native rule (839–1032)

Anatolian dynasty

Docibilan dynasty

Lombard period (1032–1064)

In 1041, Guaimar gave direct control and his title to the count of Aversa. In 1058, Gaeta was made subject to the count of Aversa, by then prince of Capua.

Norman period (1064–1140)

These were vassals of the princes of Capua. Princes Richard I and his son Jordan I used the titles duke and consul from 1058 and 1062 respectively. In 1140, Gaeta went directly to the king of Sicily, Roger II. Under the Hautevilles and the Hohenstaufen, sovereigns continued issuing coinage as rulers of Gaeta until 1229.
