Abraham Seneor or Abraham Senior (Segovia 1412 - 1493) was a Sephardic rabbi, banker, politician, patriarch of the Coronel family and last Crown rabbi of Castile, a senior member of the Castilian hacienda (almojarife of the Castile or royal administrator). In 1492, at the age of 80, he converted to Roman Catholicism, taking the name Ferran, Fernan or Fernando Núñez Coronel, thus founding the noble lineage of Coronel.
