Frederick Greenwood was an English journalist, editor, and man of letters. He completed Elizabeth Gaskell's novel Wives and Daughters after her death in 1865.

Wives and Daughters, An Every-Day Story is a novel by English author Elizabeth Gaskell, first published in the Cornhill Magazine as a serial from August 1864 to January 1866. It was partly written whilst Gaskell was staying with the salon hostess Mary Elizabeth Mohl at her home on the Rue de Bac in Paris. When Mrs Gaskell died suddenly in 1865, it was not quite complete, and the last section was written by Frederick Greenwood.
