The number of active editors (registered accounts making 5+ edits in a given month) has been stable at the English Wikipedia since about 2013. Even though the overall volume is holding steady, we miss many of the individuals who used to contribute here.

This is a partial list of Wikipedians who no longer edit the English Wikipedia and are considered missing by the community. This page includes editors whose most recent edit was before 2009.

The entries with the mop icon beside their names are Wikipedia administrators, or have been at one time (many are procedurally desysopped due to inactivity; see also Wikipedia:List of administrators/Inactive). All dates featured on this page correspond with UTC times.
