1972–73 Eerste Divisie

The Dutch Eerste Divisie in the 1972–73 season was contested by 20 teams, one less than in the previous year. This was due to the merger of Blauw-Wit Amsterdam with eredivisie-club DWS to form FC Amsterdam. Roda JC won the championship.

It was the first season in which a promotion competition was held. In this promotion competition, four period winners (the best teams during each of the four quarters of the regular competition) played for promotion to the eredivisie.
