Alfonso Jofré Tenorio (died 16 April 1340) was the Admiral of Castile from 1314 until his death.
He participated in a war against the Emirate of Granada in 1316, and led a blockade in 1326 during which he defeated the Granadan-Marinid fleet.
In 1333 he participated in the defense of Gibraltar against a Marinid-Granadan siege, but Castile was defeated and he signed a 1334 treaty that formalised the cession of the town.
He died in a naval battle against the Marinid fleet of Abu al-Hasan Ali on the Strait of Gibraltar.
