Sheila Anne Elizabeth Heaney, CB, MBE, TD (11 June 1917 – 1 February 1991) was a British Army officer.
She joined the Auxiliary Territorial Service shortly before the Second World War and served in the UK, East Africa and Palestine.
After the war she transferred to the newly formed Women's Royal Army Corps (WRAC).
Heaney rose through the ranks and was honoured with appointment as a Member of the Order of the British Empire.
She was promoted to the rank of brigadier, appointed director of WRAC and Aide-de-camp to Queen Elizabeth II in 1970.
As part of her role Heaney visited the United States to study their ongoing integration of women into the army and recommended that the process proceed in the UK on a gradual basis.
She instituted changes to make it easier for women in the British Army to choose their branch of service.
After her retirement in 1973, she lived in Edinburgh where she volunteered with the Women's Royal Voluntary Service and supported a local hospice.
