Reginald Fitz Jocelin[a] (died 26 December 1191) was a medieval Bishop of Bath and an Archbishop of Canterbury-elect in England.

Reginald was the son of Josceline de Bohon, the Bishop of Salisbury, although he was possibly born before his father became a priest.

[7] Reginald probably studied at Paris sometime during 1163 or 1164, as he had a letter of introduction from Pope Alexander III to Hugues de Champfleury, Bishop of Soissons, the chancellor of Louis VII.

These negotiations included papal nuncios and most of the Norman bishops and prominent abbots, as well as the royal clerks.

[9] Reginald was one of the main clerics working for King Henry during the dispute with Becket, along with John of Oxford, Richard of Ilchester, and Geoffrey Ridel.

Henry's plans to reward the four with bishoprics in late 1170 probably precipitated the final crisis that led to Becket's murder.

Ralph de Diceto, however, states that Reginald swore an oath that he was uninvolved in the death of Becket and that his birth took place before his father became a priest.

[5] During the dispute, Reginald's friend Peter of Blois wrote him a letter, which is still extant,[c] encouraging him to persevere.

[14] As a bishop, Reginald was kept busy attending the king's councils and the royal court, but also took part in the 1178 mission to Toulouse, led by Cardinal Pierre of San Crisogono, which attempted to deal with the Cathar heretics there.

[12] Before his death, he was admitted as a confrater of Christ Church Priory, Canterbury, and was buried in the habit of a Benedictine monk.

[19] According to a monk of Eynsham Abbey, after Reginald's death "he performed miraculous cures for certain weak and sick people.
