The Studentenstam De Delftsche Zwervers is a student society in Delft, Netherlands. Dating from 1915, it is the world's oldest student Scouting group, first as a club for former Scouts, from 1920 as a Rover crew. They are housed in the Scout Centre "Kruithuis", the monumental gunpowder ammunition dump of the Dutch Republic, designed in 1660 by Pieter Post. The members are students at the Delft University of Technology and other higher education institutions.
