Dame Sarah Elisabeth Mullally DBE (née Bowser; born 26 March 1962) is a British Anglican prelate and former nurse.

While studying for A levels she decided to become a nurse rather than a doctor because she wanted to apply a holistic approach to patient care.

[4] In 1992, she completed a Master of Science (MSc) degree in inter-professional health and welfare studies at London South Bank University.

In 1999 she was appointed as Chief Nursing Officer and Director of Patient Experience for England: she was the youngest person to hold these positions.

[4][12] In 2004, Mullally left her position as Chief Nursing Officer to pursue full-time CofE ministry.

[4][16] She graduated with a Master of Arts (MA) degree in pastoral theology from Heythrop College, University of London in 2006.

[22] Between her confirmation and her installation, she was licensed as an honorary assistant bishop in the Diocese of Exeter so that she was able to carry out engagements related to her former see.

[35] In relation to same-sex relationships, she stated in 2017 that "It is a time for us to reflect on our tradition and scripture, and together say how we can offer a response that is about it being inclusive love.

"[36] In 2022, Mullally supported the observance of LGBT+ History Month and the launch of an Advisory Group aimed at advising the diocese on "pastoral care and inclusion of LGBT+ people in the life of our church communities".

[39][40] Following her appointment as Bishop of London, Mullally moved into the Old Deanery of St Paul's, making alterations to the property, including the construction of an oratory in a former laundry room in which she prays the rosary and other Marian devotions and presides at weekly eucharistic adorations.

[5] In the 2005 New Year Honours, Mullally was appointed Dame Commander of the Order of the British Empire (DBE) in recognition for her contribution to nursing and midwifery.
