The 1977 Spanish general election was held on Wednesday, 15 June 1977, to elect the Constituent Cortes Generales of the Kingdom of Spain. All 350 seats in the Congress of Deputies were up for election, as well as all 207 seats in the Senate.

It was the first free election held in Spain since 1936, prior to the outbreak of the Spanish Civil War. It was called by Prime Minister Adolfo Suárez as part of the political reform of the Francoist regime, ongoing since shortly after Francisco Franco's death in 1975 and promoted by his successor, King Juan Carlos I. Its aim was to elect a Constituent Cortes that was to draft a new constitution, which would ultimately lead to the repealing of the Fundamental Laws of the Realm and the culmination of the country's peaceful transition to democracy.

The Union of the Democratic Centre (UCD), the electoral coalition created to serve as Suárez's political platform in government, emerged as the largest party overall, albeit 11 seats short of an absolute majority. The election surprise was the Spanish Socialist Workers' Party (PSOE) of Felipe González, which—supported by the German SPD and running a campaign intended to highlight González's youth and charisma—won 118 seats and became the main left-of-centre party by a wide margin. The Communist Party of Spain (PCE), which had been the main opposition force to the dictatorship, and the right-wing People's Alliance (AP) of former Francoist minister Manuel Fraga, performed below expectations. Turnout was high at 78.8%, the second highest for any nationwide election held ever since.
