The Senate of the Dominican Republic () is the upper house in the bicameral legislature of the Dominican Republic, and together with the Chamber of Deputies makes up the Congress.
The composition and powers of the Senate are established in Third Title, Chapter 1 in the First Section of the Dominican Constitution. Each province, and the Distrito Nacional, regardless of population, is represented by one senator who serves for a four-year term, with possibility of reelection. The Senate Chamber is located in the west wing of the Congress Palace, in Santo Domingo. The Chamber of Deputies convenes in the east wing of the same building.
The Senate has several advice and consent powers not granted to the Chamber of Deputies, including consenting to treaties, loans and contracts as a precondition to their ratification and consenting to or confirming appointments the members of Chamber of Accounts, Central Electoral Board and ambassadors. The Senate is widely considered both a more deliberative and more prestigious body than the Chamber of Deputies. Due to its smaller size and statewide constituencies, the Senate has historically had a more collegial and less partisan atmosphere.
The constitution of the Dominican Republic states that to be a senator, one must be a Dominican in full exercise of civil and political rights, have attained twenty-five years old, and be a native of the territorial demarcation that choose or have resided there for at least five consecutive years. In consequence:
The members of the Senate in Dominican Republic are elected by the D'Hondt method in relationship with the deputies. The terms for serving as senator are unlimited, one term corresponds to four years.
