Vlekkem is a sub-municipality of Erpe-Mere in Flanders, Belgium.

It is located on the Molenbeek in the Denderstreek, southeast of East Flanders and belongs to the Arrondissement of Aalst.

In this charter where the emperor Koenraad II recognized the Abbey Sint-Pietersabdij in Ghent and their possessions, they spoke of "et in Bursinghem et terram in Ottringhem et terram in Flachem".

In the opinion of the historian Föstermann, the name of the village is derived from a personal name.

The Molenbeekroute is a cycle track network, known primarily for the mills of the municipality Erpe-Mere and two brooks that can be found there, which both have the name Molenbeek (mill brook).
