Donald Ibrahim Swann (30 September 1923 – 23 March 1994) was a British composer, musician, singer and entertainer.

His father, Herbert Alfredovich Swann, was a Russian doctor of English descent, from the expatriate community that started out as the Muscovy Company.

His mother, Naguimé Sultán Swann (born Piszóva), was a Turkmen-Russian nurse from Ashgabat, now part of Turkmenistan.

Swann's great-grandfather, Alfred Trout Swan, a draper from Lincolnshire, emigrated to Russia in 1840 and married the daughter of the horologist to the tsars.

In 1942 he registered as a conscientious objector and served with the Friends' Ambulance Unit (a Quaker relief organisation) in Egypt, Palestine and Greece.

[6] A lifelong friendship with Sydney Carter resulted in scores of songs, the best known being "The Youth of the Heart" which reappeared in At the Drop of A Hat, and a musical Lucy and the Hunter.

In the later years of his life he 'discovered' Victorian poetry and composed some of his most profound and moving songs, settings of William Blake, Emily Dickinson, Christina Rossetti, Oscar Wilde and others.
