Anna Bartlett Warner (August 31, 1827 – January 22, 1915) was an American writer, the author of several books, and of poems set to music as hymns and religious songs for children.

Some stanzas of this appear in modern hymnals rewritten by David Rutherford McGuire.

She wrote some books jointly with her sister Susan Warner (Elizabeth Wetherell) which included Wych Hazel (1853), Mr. Rutherford's Children (1855) and The Hills of the Shatemuc (1856).

[3] Her former family home is now a museum on the grounds of The United States Military Academy [2] which was opposite the house during her lifetime and where her uncle had been chaplain from 1828 to 1838.

[3] The Constitution Island Association have worked hard to maintain the house and restore the gardens so that they are similar to their appearance in Anna Warner's lifetime, following her month-by-month descriptions of life on Constitution Island, as written in Gardening by Myself.
