Norwegian Augustana Synod (NAS) was a Lutheran church body in the United States from 1870 to 1890.
The group's original name was the Norwegian-Danish Augustana Synod in America.
The NAS was created out of the Scandinavian Augustana Synod (SAS) in 1870.
At the same time the NAS was being formed, another group of Norwegians and Danes created out of the SAS the Conference of the Norwegian-Danish Evangelical Lutheran Church of America (The Conference).
The Conference just wanted the three ecumenical creeds, Luther's Small Catechism and the Unaltered Augsburg Confession.
