The Downtown Eastside Residents Association (DERA) was a non-profit society in the Downtown Eastside area of Vancouver, operating from 1973 until 2010. The association was founded by Bruce Eriksen, Libby Davies, Jean Swanson, University of Victoria professor Calvin Sandborm and other residents of the Downtown Eastside. Membership was restricted to those who live within the neighbourhood's boundaries. The association's original aims are outlined in its Mission Statement.
