The centre-back saw off competition from Manchester City trio Sergio Aguero, Aymeric Laporte and Raheem Sterling, as well as Burnley’s Ashley Barnes and Manchester United midfielder Paul Pogba, to clinch the award.
It’s the second time this season Van Dijk has claimed the prize having previously won it in November.
The Netherlands captain played all four league games for Liverpool during the month, keeping three clean sheets and scoring two goals.
