Restitutus (fl. 314) was a Romano-British bishop, probably from Londinium (London), one of the British delegation who attended the church synod or Council held at Arles (Arelate), in Gaul, in AD 314. The list of those who signed the Acta, the decisions made by the council, included three bishops, along with a "presbyter" and a "deacon", from Britain. The British bishops were Eborius "de civitate Eboricensi" – from the city of Eboracum (York); Restitutus "de civitate Londenensi" – from the city of Londinium (London); and Adelfius "de civitate Colonia Londenensium" – from the "colonia of the people of London".
