Ajax has won its fourth consecutive Eredivisie title following Sunday afternoon's 1-1 draw with Heracles.
A point at the Polman Stadion was enough for the Godenzonen to wrap up the championship with one round to spare, having collected 70 points from 33 games.
It is the first time in Ajax's illustrious history it has won the Dutch title four years in a row.
Frank de Boer's men were joint first with Vitesse heading into the winter break, but a string of impressive results in the second half of the season saw them pull clear of their rivals.
The 43-year-old De Boer has now matched Louis van Gaal's achievement of capturing four Eredivisie titles. Only Rinus Michels (five) and Guus Hiddink (six) have won the Dutch top flight on more occasions as coach.
Ajax missed the chance to clinch its first domestic double since 2001-02 when it lost to PEC Zwolle in the KNVB Beker final last week.
