The Eastern Carolina Cluster of the Thomas Jefferson District of the Unitarian Universalist Association of Congregations generally includes those UU or Universalist congregations in North Carolina on or east of I-95, but is open to participation from churches from outside that area who, often for reasons of congregation size or rural character, have more in common with us than with other congregations in their cluster.

The cluster is an informal grouping of congregations that was begun by RE Directors, chairs, and volunteers for mutual support and sharing of ideas. The cluster has no dues or officers, and meetings are called and hosted by congregations on a voluntary basis. Within recent years, cluster meetings have been hosted by the Greenville and New Bern congregations.
