Peter Andrew Comensoli (born 25 March 1964) is an Australian Catholic prelate who was named the ninth Archbishop of Melbourne on 29 June 2018.

Comensoli studied at St Paul's (now Holy Spirit) College, Bellambi, New South Wales, and studied commerce at the University of Wollongong while working for four years in the banking sector before switching to theology.

Comensoli obtained a Licentiate of Sacred Theology (STL) from the Alphonsian Academy in Rome in 2000, a Master of Letters (MLitt) degree in moral philosophy from the University of St Andrews in 2007 and a Doctor of Philosophy (PhD) degree in theological ethics from the University of Edinburgh.

[3][4] His doctoral thesis was titled "Recognising persons: the profoundly impaired and Christian anthropology" and was submitted in 2012.

[13] Comensoli personally vouched for Cardinal Pell by signing a letter of support in 2015 ahead of the Royal Commission into Institutional Child Sexual Abuse, describing him as a "man of integrity",[14] and considered him a personal friend.
