The National Council of the Churches of Christ in the USA, usually identified as the National Council of Churches (NCC), is the largest ecumenical body in the United States, comprising member from 38 Christian faith groups.

The NCC sponsored the multi-denominational research effort that produced the Revised Standard Version (1952) and the New Revised Standard Version (1989), and holds the copyrights to both translations.

In 2017 the NCC commissioned the Society of Biblical Literature (SBL), the world's leading international association of biblical scholars, to review and update the NRSV. The SBL review panel included seven general editors and fifty-six book editors.
