The Council of Toul was a Frankish synod convoked by Theudebald, King of Austrasia, that convened in Toul on 1 June 550. It is not known how many bishops attended. It extended to the ecclesiastical provinces of Reims and Trier and perhaps beyond. The diocese of Toul was a suffragan of Trier. The metropolitan bishop, Nicetius of Trier, was certainly in attendance.
