Howard West Kilvinton Mowll (2 February 1890 – 24 October 1958) was the Anglican Bishop of Western China from 1925 to 1933, and Archbishop of Sydney from 1933 until his death in 1958.

As a staunch evangelical, upon returning from the mission field of Western China (Sichuan), Mowll experienced early difficulties in a predominantly liberal church before rising to national prominence during the war years.

Within a month of World War 2 starting he had formed the Church of England National Emergency Fund, (CENEF), which was supported with volunteers and fundraising by the Sydney Diocesan Churchwomen's Association.

To continue to help ex service people after the war and youth work, CENEF raised funds to buy 201 Castlereagh Street, Sydney, and Rathane in the Royal National Park.

CENEF leveraged the Castlereagh Street building to buy land at Gilbulla and 117 acres in Castle Hill for a retirement village.
