List of the oldest synagogues in the United States
The designation of the oldest synagogue in the United States requires careful use of definitions, and must be divided into two parts, the oldest in the sense of oldest surviving building, and the oldest in the sense of oldest congregation. Even here, there is the distinction between old synagogue buildings that have been in continuous use as synagogues, and those that have been converted to other purposes, between buildings that have been in continuous use as synagogues and those, such as the Touro, that were shuttered for many decades, and between early established congregations that have been in continuous existence and early congregations that ceased to exist.
Oldest congregations 
Sephardi congregations 
All of the oldest congregations in the new world were founded by Sephardi Jews and followed the Sephardic liturgy.
- Congregation Shearith Israel, 1655, in New York City, is the oldest congregation in the United States, its present building dates from 1897.
- Congregation Jeshuat Israel, ca. 1658, in Newport, Rhode Island is dated to sometime after the arrival of Jews in 1658 and prior to the 1677 purchase of a communal cemetery, now known as Touro Cemetery. Prayers were conducted in private homes until Congregation Jeshuat Israel, the Touro Synagogue, was established in the 1750s. In much of the nineteenth century no Jews lived in Newport and the ownership of the building and synagogue were entrusted to Congregation Shearith Israel.
