The Margaret MacDonald Memorial is a sculpture by Richard Reginald Goulden, beside the path at the north edge of the public park at Lincoln's Inn Fields, London.

The memorial comprises a public seat within an alcove created by a granite surround, on which is mounted a bronze sculptural group portraying MacDonald kneeling with her arms outstretched protectively around a group of nine cherubic infant children who are laughing and playing.

An inscription carved below the top edge of the stone surround reads: THIS SEAT IS IN MEMORY OF MARGARET MACDONALD WHO SPENT HER LIFE IN HELPING OTHERS.

A bronze plaque mounted on the back of the seat list biographical details of her birth, marriage, and life: SHE WAS THE DAUGHTER OF JOHN & MARGARET GLADSTONE / SHE WAS BORN IN KENSINGTON IN 1870 · WAS MARRIED TO / RAMSAY MACDONALD IN 1896 AND LIVED WITH HIM AT / 3 LINCOLN'S INN FIELDS ·· HERE HER CHILDREN WERE / BORN AND HERE SHE DIED IN 1911 · SHE BROUGHT JOY / TO THOSE WITH WHOM AND FOR WHOM SHE LIVED AND / WORKED · HER HEART WENT OUT IN FELLOWSHIP TO HER / FELLOW WOMEN & IN LOVE TO THE CHILDREN OF THE PEOPLE / WHOM SHE SERVED AS A CITIZEN AND HELPED AS A SISTER · / SHE QUICKENED FAITH AND ZEAL IN OTHERS BY HER LIFE AND / TOOK NO REST FROM DOING GOOD.

The bronze sculpture was made by Goulden, to a design which has been attributed to MacDonald's widower, and cast at A. B.
