Barbara McKenzie-Smith (7 July 1902 – 17 December 1996) was a painter, mostly doing paintings on commission, and a number of her paintings are hanging in various country houses all over England. One of them is (or was) on display at the Tate Gallery in London. Her specialty was country and still life scenes, including homes in the country. She took copious notes, and hoped to publish them one day.

She was educated at the Perse School for Girls and the Slade School, and was associated with the Bloomsbury group as a young person. Her friends included Leonard Woolf, the husband of Virginia Woolf, and Leonard's close friend, the illustrator, Trekkie Parsons.

She had one son, John Paul, by John Rodker. After her marriage with John Rodker broke up, she married Edward A. Morrison III, an American citizen living in England (he joined the RAF and rose to the rank of Wing Commander), and they had a son, Thomas A. Morrison, in 1950. After the marriage, John Paul's name was changed by Deed poll to John Paul Morrison.

For about the last 30 years of their lives, she and Edward Morrison lived quietly in various locations near Dolgellau, N. Wales.

She is buried with Edward Morrison at Llanelltyd, Gwynedd, N. Wales.
