The British Geriatrics Society (BGS) is the professional body of specialists in the healthcare of older people in the United Kingdom.

Membership is drawn from doctors, nurses, allied health professionals, researchers and others working in the field of geriatric medicine with a particular interest in improving healthcare for older people.

Basil Mackenzie, 2nd Baron Amulree at the ministry of health, Joseph Harold Sheldon in Wolverhampton, Marjory Warren, Trevor Howell in Croydon and Oxford's Lionel Cosin were some of the founders of the Medical Society for the Care of the Elderly in 1947.

[1] Its purpose was "the relief of suffering and distress amongst the aged and infirm by the improvement of standards of medical care for such persons, the holding of meetings and the publication and distribution of the results of such research".

Age and Ageing, which is published by Oxford University Press, is the official journal of the British Geriatrics Society, publishing peer reviewed original articles and commissioned reviews on geriatric medicine and gerontology.
