Elizabeth Martha Anne "Pattie" Deakin CBE (née Browne; 1 January 1863 – 30 December 1934) was a leading advocate for creches, kindergartens and playgrounds in Australia.

She was the eldest daughter and fifth of eleven children born to Elizabeth (née Turner) and Hugh Junor Browne.

She was initially educated by a governess, and then from the age of 12 attended Grantown House, "a fashionable ladies' college [...] patronised by the Anglican establishment".

[4] Her "extraordinary capacities as a medium" were recounted in two of her father's volumes, published in 1876 and 1888, and in Human Personality and Its Survival of Bodily Death (1903), a posthumous work by Frederic W. H. Myers.

Her father gave only qualified approval, concerned about Alfred's social standing and lack of independent means.

They lived with his parents and sister Catherine for two years before moving to a new house, "Llanarth", built nearby on land bought by Alfred's father.

Revenue from the exhibition helped form the Bush Nursing Association; Pattie became a member of the committee.

For twenty years Pattie worked with the Melbourne District Nursing Society, first as president, and subsequently as a life vice-president.

She became the first president of the Girl Guides and the only female member of the Australian Imperial Forces Canteen Fund Trust.
