Erluin (died 987) was a Benedictine monk, the first abbot of Gembloux (946–87) and also briefly the abbot of Lobbes (956–57). Diametrically opposed accounts of his character are given by the partisans of Gembloux and Lobbes. The Abbey of Gembloux was founded on lands donated by Guibert and confirmed by King Otto I in 946. Erluin was its first abbot. He continued as its abbot even during his abbacy at Lobbes. Erluin remained as abbot of Gembloux until his death in 987, when he was succeeded by his brother Heriward.
