Naden was lauded after her death for her philosophical writings, by Robert Lewins, M.D., her contributions to poetry, her support of the women's suffrage cause in popular women's periodicals, and for her "Pantheistic view of immortality" by William Ewart Gladstone, in which he ranked her among the nineteenth century's top female poets. Lewins founded the Constance Naden Medal at Mason College in her honour, which is awarded each year, first for the "best competitive philosophical essay" and now for the best Faculty of Arts master's degree thesis at the University of Birmingham. Lewins also commissioned a bust of Naden which he presented to Mason's College. It sits on a plinth of three books, the spine of which are inscribed "Songs and Sonnets of Springtime" and "A Modern Apostle, The Elixir of Life, etc." on the front and "Induction and Deduction and Hylo-Idealism" on the back. It was originally placed in the college's library. Mason College became the University of Birmingham in 1900, and the bust stands in the Cadbury Research Library Reading Room.
