Eliza Marsden Hassall (2 November 1834 – 26 December 1917) was an Australian lay leader of the Anglican church and a philanthropist.
She was born at "Denbigh", in Cobbitty, New South Wales, the seventh of eight children of Thomas Hassall, a colonial minister, and his wife Ann, the eldest daughter of Samuel Marsden.
She assisted in the Sunday school programs at Heber Chapel, which her father had built for the benefit of the workers at the Denbigh estate, and at St. Paul's Church, in Cobbity, beginning in 1842.
She is recorded as having told a niece to break off an engagement with a young man, at whatever cost to herself, on the basis of his lacking good character, and as telling a sister-in-law that "the lessons affliction is sent to teach us is to be more sympathetic and forgiving to others.
[1] In July 1880, she helped in the formation of the New South Wales brand of the Young People's Scripture Union,[2] and later became secretary of that group.
The Deaconess Institute at Redfern took control of Marsden House and continued in the work of training woman missionaries.
