Executive branch of the government of Puerto Rico in the context of "Lieutenant Governor (United States)"

The government of Puerto Rico encompasses the local administrative structure of the archipelago and island of Puerto Rico, an unincorporated territory of the U.S. organized under the Constitution of Puerto Rico since its establishment as the Commonwealth of Puerto Rico in 1952. The government is a republican democracy divided into three branches: the law-implementing executive, the law-making legislative, and the law-interpreting judicial. The Governor is the chief executive, the Legislative Assembly is the legislature, and the Supreme Court is the highest court of the territory, which is divided into 78 municipalities, each one headed by a strong mayor and a unicameral legislature. Like U.S. states and other U.S. territories, Puerto Rico is subject to the sovereign jurisdiction of the U.S. federal government.

With the American annexation of Puerto Rico during the Spanish–American War, the U.S. established a military government to administer the unincorporated territory from 1898 to 1900, when it was replaced by a civil insular government organized under the organic acts of the Foraker Act from 1900 to 1917 and the Jones–Shafroth Act from 1917 to 1952. The Constitution of Puerto Rico established the Commonwealth of Puerto Rico and its government under the continued status of unincorporated territory in 1952. With the ratification of the constitution, the full authority and responsibility for the local administration of Puerto Rico was vested in the residents of Puerto Rico, resulting in complete self-governance within the archipelago and island.

Elections in Puerto Rico are guaranteed by Article Six of the Constitution of Puerto Rico and the Electoral Code of Puerto Rico for the 21st Century Act. All processes are overseen and managed in whole by the Puerto Rico State Elections Commission; an autonomous agency of the executive branch of the government of Puerto Rico.

La Fortaleza (English: "the fortress"), officially the Palacio de Santa Catalina ("Saint Catherine's Palace"), is the official residence and workplace of the governor of Puerto Rico. Located in the historic quarter of Old San Juan in the capital municipality of San Juan, it has served as the governor’s residence since the 16th century, making it the oldest executive mansion in continuous use in the New World. Built as a medieval fortress from 1533 to 1540 by orders of King Charles I of Spain, and remodeled to its present Neoclassical style in 1846 by orders of Governor Rafael Arístegui y Vélez, it was the first fortification erected by the Spanish on San Juan Islet to defend San Juan Bay, the harbor of Old San Juan. Alongside El Morro, San Cristóbal, and other forts part of the Walls of Old San Juan, it protected strategically and militarily important Puerto Rico, or La Llave de las Indias (The Key to the Indies), from invasion by competing world powers and harassment by privateers and pirates during the Age of Discovery and Sail. It was designated a World Heritage Site in 1983.

Situated in the western end of San Juan Islet in the Old San Juan historic quarter, La Fortaleza, seat of the executive branch, is about 1 mile (1.6 km) from the Capitol of Puerto Rico, seat of the legislative branch, in the center of the Islet in the Puerta de Tierra historic district, and 2 miles (3.2 km) from the Supreme Court Building, seat of the judicial branch, in the eastern end of the Islet in Puerta de Tierra.

The governor of Puerto Rico (Spanish: gobernador de Puerto Rico) is the head of government of the Commonwealth of Puerto Rico, an unincorporated territory of the United States. Elected to unlimited four-year terms through popular vote by the residents of the archipelago and island, the governor is the head of the executive branch of the government of Puerto Rico and the commander-in-chief of the Puerto Rico National Guard. Currently, Jenniffer González-Colón is serving as the 190th governor of Puerto Rico.

The governor has a duty to enforce local laws, to convene the Legislative Assembly, the power to either approve or veto bills passed by the Legislative Assembly, to appoint government officers, to appoint justices, and to grant pardons. Since 1948, the governor has been elected by the people of Puerto Rico. Prior to that, the governor was appointed either by the king of Spain (1510–1898) or the president of the United States (1898–1948).

The Foraker Act (Pub. L. 56–191, 31 Stat. 77, enacted April 12, 1900), officially called the Organic Act of 1900 and most commonly known by the name of its sponsor, Senator Joseph B. Foraker, (R-Ohio), is an organic act of the 56th United States Congress that was signed into law by President William McKinley on April 12, 1900. The Act replaced the military government of Puerto Rico, which was established by the United States after the annexation of the archipelago and island during the Spanish–American War in 1898, with a civil insular government under the continued federal jurisdiction of the United States as the local administration of an unincorporated territory. It served as the primary organic law for the government of Puerto Rico and its relation with the United States until it was superseded by the Jones–Shafroth Act of 1917.

The Foraker Act established a civil government in Puerto Rico modeled after the federal government of the United States. It divided the local government of the unincorporated territory into three branches: an executive, consisting of a Governor and an 11-member Executive Council appointed by the President of the United States, a legislative, composed of bicameral Legislative Assembly, with the Executive Council as its upper chamber and a 35-member House of Delegates elected by the residents of Puerto Rico as its lower chamber, and a judicial, headed by a chief justice and a district judge appointed by the President. The Act created the office of Resident Commissioner, a non-voting member to the United States House of Representatives elected by the residents of Puerto Rico. It also established Puerto Rican citizenship and extended American nationality to Puerto Ricans.

The Puerto Rico State Commission on Elections (Spanish: Comisión Estatal de Elecciones de Puerto Rico, CEEPR or CEE-PUR) is the government agency of the executive branch of the government of Puerto Rico that oversees and manages elections in Puerto Rico as well as guaranteeing the right to vote to its citizens. The agency was created on December 20, 1977 by Act No. 4 of 1997.
