Overview

The 1991 Primera División de Chile marked the 59th season of the country's premier professional football competition. Organized by the Asociación Nacional de Fútbol Profesional (ANFP), the league featured a competitive format involving 16 clubs from across Chile.

This season was notable for its structure and the dominance of Colo-Colo, who emerged as champions after a strong campaign. The league operated under a split-season format, a common practice in Latin American football, with aggregate standings determining final rankings and continental qualification.

Colo-Colo claimed the 1991 title, marking their 17th championship in Chilean football history and solidifying their status as the nation's most successful club.
The league season began in March 1991 and concluded in December, featuring a total of 30 regular-season matches per team under the Apertura and Clausura system.
Teams earned three points for a win, one for a draw, and zero for a loss, following standard FIFA scoring rules adopted globally.
Universidad de Chile, one of the most popular clubs, finished in the top half of the table but failed to secure the title despite strong home support.
The bottom two teams, Deportes Concepción and Santiago Wanderers, were relegated to the Primera B at the end of the season based on cumulative performance.

How It Works

The 1991 Primera División used a split-season format common in South American leagues, combining sporting tradition with logistical planning. This structure allowed for multiple champions or a final playoff, depending on the year’s rules.

Apertura Tournament: The first half of the season, played from March to July, featured all 16 teams in a single round-robin format. The winner advanced to contention for the overall title.
Clausura Tournament: The second half, from August to December, mirrored the Apertura with another round-robin. The Clausura champion was determined separately but contributed to aggregate standings.
Aggregate Table: Final rankings were based on combined points from both tournaments, used to determine relegation and CONMEBOL competition qualification.
Relegation System: The two teams with the lowest points-per-game average over the past three seasons were demoted, emphasizing long-term performance over a single year.
CONMEBOL Qualification: The champion, Colo-Colo, earned a spot in the 1992 Copa Libertadores, South America’s premier club competition.
Home and Away Fixtures: Each team played 30 matches—15 home and 15 away—ensuring balanced competition across the league calendar.
