The 1991 Castilian-Leonese regional election was held on Sunday, 26 May 1991, to elect the 3rd Cortes of the autonomous community of Castile and León. All 84 seats in the Cortes were up for election. The election was held simultaneously with regional elections in twelve other autonomous communities and local elections all throughout Spain.

The preceding legislature had seen José María Aznar forming a minority government of People's Alliance (AP) in 1987 through the abstention of the Democratic and Social Centre (CDS) and the support of the People's Democratic Party (PDP) and the Independent Solution (SI) of Burgos mayor José María Peña San Martín. In May 1989, following AP's re-foundation into the People's Party (PP) earlier that year, the CDS joined the cabinet as a coalition partner, granting the regional government an overall majority in the Cortes. In September 1989, Aznar resigned in order to become the PP's leading candidate for the 29 October general election—and eventually, PP national president in April 1990—, with the regional presidency being granted to Jesús Posada. However, Posada renounced contesting the party's candidacy for re-election in January 1991, following Aznar's decision to pick Juan José Lucas as regional candidate instead.

The election saw the PP secure its first absolute majority in the region, virtually ensuring the election of Lucas to the regional presidency. The CDS, on the other hand, saw its support collapse from 18 to 5 seats, with the PP's majority leaving the party out of government. The opposition Spanish Socialist Workers' Party (PSOE) slightly increased its vote share and seat count compared to its 1987 result, whereas United Left (IU) entered the Cortes for the first time with one seat.
