Conrad I, Count of Oldenburg

Conrad I (documented 1313–1347) was Count of Oldenburg, the eldest son of Count John II by his second wife, Hedwig of Diepholz. From 1324 he ruled jointly with his elder half-brother John III, alone after John's death in 1342, and from 1345 together with his nephew John IV.

On 6 January 1345 the two counts granted the city of Oldenburg Bremen town law to attract foreign merchants. He was married to Ingeborg of Holstein and died in 1347, leaving two sons, Conrad II and Christian V.
