Anthony Michael "Tony" Bayfield CBE is a Reform rabbi and former President of the Movement for Reform Judaism, the second largest organisation of synagogues in Britain.

Bayfield was born in 1946 in Ilford, Essex (now in Greater London), the elder son of Sheila (née Mann) and Ron Bayfield, a head teacher.

He was educated at the Royal Liberty Grammar School in Romford and Magdalene College, Cambridge. He studied law and had a doctoral place at the Cambridge Institute of Criminology and then moved to the Leo Baeck College to train as a rabbi. He received rabbinic ordination (semichah) in 1972 from rabbis John Rayner, Hugo Gryn and Louis Jacobs.

After ten years as a congregational rabbi at North West Surrey Synagogue, Bayfield became director of the Sternberg Centre for Judaism in Finchley in 1985. He was head of the Movement for Reform Judaism from 1994 (when the organisation was known as Reform Synagogues of Great Britain) until 2011. From 2011 to 2016 he was President of the organisation.

Bayfield was awarded a CBE in the 2011 New Year Honours List for services to Reform Judaism.

London's National Portrait Gallery holds a photographic portrait of him by Don McCullin.

Tony Bayfield married Linda Rose, a teacher and Jewish educator in 1969; she died in 2003. In 2011, he met Jacqueline Fisher, whom he married in a small ceremony in June 2021.

Bayfield has three children and six grandchildren. His younger daughter, Miriam Berger, received semichah in July 2006 and is a respected rabbi in her own right.
