 General elections were held in Puerto Rico on Tuesday, November 6, 2012, to elect the officials of the Puerto Rican government that would serve for the next four years, most notably the Governor of Puerto Rico. A status referendum was held on the same date.
 The gubernatorial elections were won by then-Senator Alejandro García Padilla from the Popular Democratic Party (PPD), who defeated incumbent governor Luis Fortuño from the New Progressive Party (PNP) in a close election. This election marked the second time in more than 40 years that six parties participated in the election, the first time in more than 60 years that a status referendum was held on the same day as the general election, and the first time in Puerto Rico that absentee ballots were issued for those who were out of the country on the day of the election. As of 2023, this was the most recent time a member of the Popular Democratic Party won the governorship of Puerto Rico, and the last time a Republican did so.
 In the elections for Resident Commissioner, incumbent Pedro Pierluisi of the PNP (who caucused with the Democratic Party and who was first elected in 2008, narrowly won reelection for a second term. Pierluisi defeated his closest opponent, Rafael Cox Alomar of the PPD by almost 1.3%.
 Before the election year, the constitution of Puerto Rico provides for any qualified person to present their candidacy for a specific position. If two or more candidates from the same party present their candidacy for the same position, and they can't reach an agreement within the party, a primary election is held. This election is held within the inscribed members of each party, to select which of the candidates will represent the party in the general election.
 Both of the main parties, the PNP and PPD, held primaries for several positions on March 18, 2012.
 The primaries were held on March 18, 2012 to determine several candidates for the Senate, House of Representatives, and others.

 The campaign of the main opposing party, the PPD, focused mostly on the problems of crime, unemployment, and high utility costs, attributing them to the failure of the incumbent governor, Luis Fortuño, from the PNP. The PNP, on the other hand, focused mostly on the lack of experience of the PPD candidate, Alejandro García Padilla.
 The minority parties have directed their campaign at the inability of the main two parties to administer the country. The Puerto Ricans for Puerto Rico Party (PPR) attacked the alleged classism and social inequality of the current government, while the Working People's Party (PPT) advocated for a government more attuned to the working class.
 There were two official debates celebrated with all gubernatorial candidates. The first one was held on September 11, 2012 under the title of "Vota o Quédate Calla'o" ("Vote or Keep your Mouth Shut"). It was transmitted by the television network of Sistema Universitario Ana G. Méndez. The second debate was held on October 25, 2012 under the title of "El Gran Debate". This debate was transmitted by Telemundo and had the best TV ratings for the night with 18.7 and a 27.3% share.
 In the morning of November 7, 2012, Fortuño conceded the election to Alejandro García Padilla, just as the last votes were being counted. The margin of victory was 0.7% (or 11,049 votes) which would make it the second closest election in the island in the last 20 years. The candidates of the minority parties all received less than the required 3% to remain registered. Notably, Rogelio Figueroa (from the PPR) received only 0.4% of the vote after receiving 3% in the 2008 general elections.
 The incumbent Pedro Pierluisi from the PNP defeated the candidate from the PPD, Rafael Cox Alomar. Pierluisi managed to be reelected, despite the fact that his ballot partner, Governor Fortuño, lost against the PPD candidate. This would be the second time in the last 10 years where the governor and the resident commissioner came from different parties. The first one was after the 2004 elections where PPD candidate Aníbal Acevedo Vilá narrowly won the election, while Fortuño (PNP) was elected resident commissioner.
 The PPD won a majority of seats in the Senate of Puerto Rico, with a total of 18 out of 27. The PNP won a total of 8 seats, while the Puerto Rican Independence Party (PIP) won one seat. The PPD won the majority after two terms of being a minority. The election of a senator from the PIP also comes after one term with no senator seated. The PPD won six of the Puerto Rico Senatorial districts. The PNP won only two districts, despite winning all eight during the previous elections.
 The PPD also won a majority of seats in the Puerto Rico House of Representatives, with a total of 28 out of 51. The PNP won a total of 23 seats. The other minority parties won no seats. Like with the Senate, the PPD won the majority after two terms of being a minority.
 The PPD won a majority of the mayoralty races in the island, with a total of 46 out of 78 municipalities. The New Progressive Party (PNP) won a total of 31. One of the most notable races featured PPD candidate Carmen Yulín Cruz defeating incumbent Jorge Santini (PNP) for the mayoralty of the capital city of San Juan after 12 years in the seat.
