Tam Lin is a 1991 contemporary fantasy novel by United States author Pamela Dean, who based it on the traditional Scottish border ballad "Tam Lin".

The protagonist of Tam Lin is Janet Carter. Written in the indirect third person, from Carter's point of view, the novel is set during her years as a student in the early 1970s at the fictional Blackstock College in Minnesota. The characters include her fellow students, professors at the college, her family, and a childhood friend. The plot combines the story of a young woman's life at college with a retelling of the traditional Scottish fairy ballad "Tam Lin".

Tam Lin is a late 20th-century urban fantasy or fantasy of manners. The story touches on themes including college education, sexuality, contraception, abortion and pregnancy. Dean has referred to this novel as a "love poem" to "my college, and ultimately to the study of English literature."^[1]

The novel Tam Lin is based on the traditional Scottish border ballad Tam Lin.^[2]

The novel also contains many quotations and allusions. Most of the quotations are from English literature and especially Shakespeare's plays,^[3] but there are also quotes from and allusions to other sources, including English folk songs. One chapter refers extensively to an in-story production of The Revenger's Tragedy.^[3] It refers to the poetic works of John Keats. The complete text of La Belle Dame Sans Merci is quoted by the novel's protagonist.^[3] Homer's Iliad is quoted and referenced by several characters, in the original ancient Greek and in English translations by George Chapman and Alexander Pope.^[3]

The novel alludes to several historical events and figures in early 1970s U.S. history, including the Vietnam War and Nixon. Carter mentions the US Supreme Court ruling allowing legal abortions in the U.S. (see Roe v. Wade).

Blackstock College is partially based on Carleton College, Northfield, Minnesota, which the author attended as an undergraduate (1971–1975). In the "Author's Note", Dean states:

Readers acquainted with Carleton College will find much that is familiar to them in the architecture, landscape, classes, terminology, and general atmosphere of Blackstock. They are earnestly advised that it would be unwise to refine too much upon this. Blackstock is not Carleton.^[4]
