New Sweden Chapel is a historic Lutheran Church building located east of Fairfield, Iowa, United States in rural Jefferson County.

The Swedish immigrant community that settled here was organized in 1845 under the leadership of Peter Cassel, a native of Kisa, Östergötland, Sweden.

The interior features a painting by Olaf Grafström, who was an art instructor at Augustana College in Rock Island, Illinois.

In 1948 the Augustana Evangelical Lutheran Church named the New Sweden Chapel as a National Synodial Shrine in recognition of its being the oldest congregation in the synod.
