2001 Categoría Primera B season

The 2001 Categoría Primera B season, (officially known as the 2001 Copa Águila for sponsorship reasons) was the 12th season of Colombia's second division football league. Deportes Quindío won the tournament for the first time and was promoted to the Categoría Primera A. After expanding the number of Primera A teams from 16 to 18, DIMAYOR organised a special promotion tournament, where the top two teams were promoted. The two DIMAYOR affiliates that were taking part in Primera B and failed to earn promotion (Cúcuta Deportivo and Unión Magdalena) were invited to compete, as well as Atlético Bucaramanga as the team that was relegated from Primera A at the end of the season, with Unión Magdalena and Atlético Bucaramanga being promoted. Edinson Castro, playing for Deportivo Rionegro, was the topscorer with 15 goals.
