Roger Alan Jupp SSC (born 1956) is a British Anglican bishop. He was the Bishop of Popondota from 2003 to 2005. He returned to parish ministry because of ill-health.

Jupp was born in London and brought up in Blackheath. He was educated at Haberdashers' Aske's Hatcham Boys' Grammar School (1968–74), St Edmund Hall, Oxford (BA Theology 1978, MA 1982), St Mary's University, Twickenham (PGCE 1996), and Chichester Theological College (1979-80). Since his time at the University of Oxford he has been interested in the history of the Church of England in the nineteenth century.

Between Oxford and commencing his training for ordination he worked as a nursing auxiliary at St Christopher's Hospice in Sydenham.

He was ordained deacon in 1980 and priest in 1981 and served as assistant curate of Newbold with Dunston (1980–83), Cowley St John (1983–85) and Islington St James with St Philip (1985–86).

He was Vicar of Lower Beeding (1986–90) and domestic chaplain to the Area Bishop of Horsham, Ivor Colin Docker (1986–91). He then became Vicar of Burgess Hill St John (1990–93) and Team Rector of Burgess Hill St John with St Edward (1993–94).

Due to the Church of England's decision to ordain women to the priesthood, Jupp spent the years 1994-97 in the Roman Catholic Church, training as a teacher at Saint Mary's College, University of Surrey (1995–96). He returned to the Church of England in 1997, receiving permission to officiate in the Diocese of Chichester and becoming assistant curate of Aldwick (1998-2000).

His friendship with the Most Reverend James Ayong, Archbishop of Papua New Guinea, led to Jupp's appointment as Principal of Newton Theological College, Popondetta, Oro Province, Papua New Guinea in 2000.

Throughout his stipendiary ministry he had been a member of the Ecumenical Society of the Blessed Virgin Mary (and a member of its council), the Society of the Holy Cross, the Church Union and the Confraternity of the Blessed Sacrament.
