Edward William Murray "Dominic" Walker OGS DL is a retired Anglican bishop. He was the Bishop of Reading, an area bishop, from 1997 to 2002 and Bishop of Monmouth from 2003 to 2013.

The Oratory of the Good Shepherd (OGS) is a dispersed international religious community, within the Anglican Communion. Members of the oratory are bound together by a common rule and discipline, which requires consecrated celibacy, and are strengthened by prayer and fellowship; they do not normally live together in community but meet regularly in chapter and retreat and report to one another on their keeping of the rule.
