1985–86 Belgian First Division

Statistics of Belgian League in season 1985–86.

Overview
It was performed by 18 teams, and R.S.C. Anderlecht won the championship, while K. Waterschei S.V. Thor Genk & Lierse S.K. were relegated.

The top two teams, Anderlecht and Club Brugge, finished level on points (though Anderlecht had a superior goal difference) and it was decided that a two-legged championship playoff would take place – a situation which had not occurred in Belgian football since 1928–29. Both of these 'test matches' were drawn: 1–1 in Brussels and 2–2 in Bruges, with Anderlecht coming back from two goals behind and holding off a late onslaught from the opposition to claim the title on the away goals rule.
