Peter Frederick Jensen (born 11 July 1943) is a retired Australian Anglican bishop, theologian and academic. From 1985 to 2001, he was principal of Moore Theological College. From 2001 to 2013, he was the Archbishop of Sydney and Metropolitan of the Province of New South Wales in the Anglican Church of Australia. He retired on his 70th birthday, 11 July 2013. In late 2007, Jensen was one of the founding members of the Global Anglican Future Conference (GAFCON), which he served as General Secretary. He stepped down in early 2019 and was succeeded by Benjamin Kwashi, former archbishop of Jos in Nigeria.

Jensen was born in Sydney and educated at Bellevue Hill Public School and The Scots College. After completing his Leaving Certificate, Jensen studied law for two years and worked as an articled clerk before he moved into primary school teaching.^{[citation needed]}

Jensen entered Moore Theological College in the late 1960s and won the Hey Sharp prize for coming first in the Licentiate of Theology, the standard course of study at that time. He also has a Master of Arts degree from Sydney University, a Bachelor of Divinity degree from the University of London and a Doctor of Philosophy (DPhil) degree from the University of Oxford. His 1976 master's dissertation was entitled "Calvinism and the Persecution of the Witches in England (1563–1604)" and his 1979 doctoral dissertation was entitled "The Life of Faith in the Teaching of Elizabethan Protestantism".^{[citation needed]}

Jensen was ordained in the Anglican Church of Australia as a deacon in 1969 and as a priest in 1970. He was a curate at St. Barnabas, Broadway, between 1969 and 1976. From 1976 to 1979, while studying for his doctorate at the University of Oxford, he was granted permission to officiate in the Diocese of Oxford, England.

From 1973 to 1976 and 1980 to 1984, he lectured in systematic and biblical theology at Moore Theological College. He was appointed Principal in 1985 and held the post until becoming a bishop in 2001. He gained a reputation as a gifted preacher and was often seen at the annual Katoomba Christian Conventions.

On 5 June 2001, Jensen became the 11th Archbishop of Sydney. He was consecrated on St Peter's Day, 29 June 2001. He called upon all churches in the Sydney diocese to aim to reach 10% of their communities by 2012. He also encouraged an unprecedented increase in church planting. Over the course of 2002–2008, 136 new congregations were started within the diocese, particularly within the Northern, Western and Wollongong regions. The number of candidates for ordination within the diocese increased from 20 to 30 per year to 40-50 by 2008.

Shortly after his appointment as Archbishop of Sydney, Jensen was accused of nepotism after nominating his brother, Phillip Jensen, as Dean of Sydney and appointing his own wife, Christine Jensen, to a lay position in a new women's ministry team. However, according to a spokesperson for Jensen, his wife was the only unpaid member of this team, and the new role was "just an extension of what she's been doing for many years, as the wife of the Moore College principal and now as the wife of the archbishop".

Jensen has a reputation with the Australian media for being an outspoken advocate for evangelical Christianity. He has spoken out on issues as diverse as abortion, euthanasia and embryonic stem cell research as well as on industrial relations. He has expressed his opposition to the ordination of women as priests, saying "the church is more like a family and, within the family, men are the spiritual guides", but believes women can be appointed to the diaconate, and has ordained women as such within the Sydney diocese. He is opposed to the ordination of women as bishops. In 2012 he declined to participate in the consecration of a woman bishop, Genieve Blackwell, within the Canberra-Goulburn diocese of the province of New South Wales "for reasons of conscience" and deputised the Bishop of Newcastle to do so. He has also opposed the ordination of non-celibate gay people as clergy.
