İbrahim I, aka Bedrettin İbrahim , was a bey of Karaman Beylik, a Turkish principality in Anatolia in the 14th century.
His father was Mahmut Bey. His elder brother Musa had succeeeded Mahmut in 1312. But soon İbrahim laid claim to throne and rebelled in 1318. Although the details of the civil war are not known, according to Ibn Battuta, the famous Arabian traveller who acted as İbrahim's envoy to Mamluk Sultanate of Egypt, he won the throne with the help of Mamluks. Between 1332 and 1340 he abdicated on behalf of his brother Halil. Upon Halil's death however, he resumed his former title. His death date is not certain. But he died no sooner than 1343 when he campaigned to Armenian Kingdom of Cilicia.
