Louise Imogen Guiney (January 7, 1861[1] – November 2, 1920) was an American poet, essayist and editor, born in Roxbury, Massachusetts.

The daughter of Gen. Patrick R. Guiney, an Irish-born American Civil War officer and lawyer,[2] from County Tipperary and Jeannette Margaret Doyle, she was raised Roman Catholic and educated at the Notre Dame convent school in Boston and at the Academy of the Sacred Heart in Providence, Rhode Island, from which she graduated in 1879.

She was a member of several literary and social clubs, and according to her friend Ralph Adams Cram was "the most vital and creative personal influence" on their circle of writers and artists in Boston[3] (see Visionists).

With Gwenllian Morgan, Guiney prepared materials for an edition and biography of the seventeenth-century Anglo-Welsh Metaphysical poet Henry Vaughan.

[8] Her life and works caught the attention of the historian and writer Eva Tenison who unusually published books about her under her own name.
