Mary Braidwood Mowle (1827–1857) was a diarist in 19th-century New South Wales.
She was born on 3 August 1827 at Durham, England and arrived in Sydney with her parents on 24 June 1836.
She began writing a diary in 1850 while living on a farm with her husband near where Canberra was later founded, and continued her diary entries after she moved to Eden.
Mowle died in Balmain, Sydney on 15 September 1857,[1] due to complications from the birth of her sixth child two weeks previously.
Her diaries were preserved and are considered valuable as they provide a female perspective on life in regional Australia at this time.
