Geoffrey I (c. 980 – 20 November 1008), also known as Geoffrey of Rennes and Geoffrey Berengar, was Duke of Brittany from 992 until his death, and also Count of Rennes (ruler of the Romano-Frankish civitas of Rennes) by right of succession. The eldest son of Duke Conan I of Brittany, he assumed the title of Duke of Brittany upon his father's death in 992. Brittany had long been an independent state, but he had little control over much of Lower Brittany.[a]
