Louise Imogen Guiney (January 17, 1861 – 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, and Jeannette Margaret Doyle, she was educated at a convent school in Providence, Rhode Island, from which she graduated in 1879. Over the next 20 years, she worked at various jobs, including serving as a postmistress and working as a cataloger at the Boston Public Library. 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 (see Visionists).
In 1901, Guiney moved to Oxford, England, to focus on her poetry and essay writing. She soon began to suffer from ill health and was no longer able to write poetry and instead concentrated on critical and biographical studies of English Catholic poets and writers.
Guiney died of a stroke near Gloucestershire, England, at age 59, leaving much of her work unfinished.
