The Bishop of St Edmundsbury and Ipswich, the Rt Rev Richard Lewis, is to retire next year.
Bishop Richard Lewis is to retire next June
The bishop will step down at the end of June 2007 after 10 years in the job, said a Church spokesman.
"Next year will mark 40 years since my ordination and a quarter of my working life's been spent in Suffolk though it feels more like 10 minutes," he said.
The process to appoint his successor begins immediately in time for the 2008 Lambeth Conference of Anglican bishops.
In addition to holding clerical posts the bishop was also a chaplain to industry in the North East during the 1970s and to agriculture in Hereford in the 1980s.
He was bishop of Taunton before coming to Suffolk in 1997. He is standing down just before the Lambeth Conference, a gathering of Anglican bishops, in 2008.
He said: "I need to give my successor sufficient time to prepare for the conference and for that person to work through all that is discussed and decided about the future of our Church."
