Captains Regent (Italian: Capitani Reggenti; Romagnol: Capitèn Regìnt) are the two heads of state of the Republic of San Marino.

[2] The practice of dual heads of government (diarchy) is derived directly from the customs of the Roman Republic, equivalent to the consuls of ancient Rome, except the Captains Regent hold no executive power.

The establishment of the regency took place during the first half of the thirteenth century, when they had the role of managing justice, a task similar to the competence of magistrates.

[3] On 1 April 2017, for the first time two women, Vanessa D'Ambrosio and Mimma Zavoli, occupied the posts of Captains Regent, until their term ended on 1 October 2017.

To be eligible for election the candidate should have the following requirements: Investiture ceremonies take place on 1 April and 1 October every year, and are prescribed by Leges Statutae Republicae Sancti Marini.

The entourage returns to the palazzo, where the official address is made and the elected Captains Regent are sworn in according to the oath describes in the Statutes of 1600.

This judgement, established by the Statutes of 1499, is now fulfilled by the Guarantors' Panel on the Constitutionality of Rules, following the revision of the Declaration on the Citizens' Rights.
