Saint-Just was buried in the cemetery des Errancis ( sometimes called cemetery des Mousseaux ). There he was buried in 1794 with several other Robespierristes.

After the Revolution, this cemetery was more or less abandoned and found again when building works started there. The bones found were transferred in the catacombs of Paris in 1817. So whatever bones of Saint-Just remained after his inhumation, there are now somewhere in the Catacombs.
