Courtney Milan, a pseudonym for Heidi Bond, is a bestselling American author of historical and contemporary romance novels. After releasing her first few books under a traditional publishing contract, Milan has self-published more recent works.

Prior to her writing career, Bond served as a law clerk for Sandra Day O'Connor of the United States Supreme Court and for Judge Alex Kozinski. As the Me Too movement gained momentum, Bond alleged that Kozinski had sexually harassed her. Following these allegations, Kozinski resigned his lifetime appointment, and Chief Justice of the United States John Roberts ordered a review of the federal judiciary's handling of sexual harassment reports.

Milan was a member of the board of directors of the Romance Writers of America (RWA) for four years, during which time she pushed for efforts to make the organization more diverse and inclusive. In late 2019, Milan was suspended by the RWA board for calling another author's book racist. She was reinstated days later after the board acknowledged irregularities in the process. The ensuing controversy resulted in the resignation of half of the RWA board of directors, the resignation of the RWA executive director, and the cancellation of the 2020 RITA Award program.

Her books have received starred reviews in Publishers Weekly, Library Journal, and Booklist. She is a New York Times and a USA Today Bestseller.

Before she started writing romance, Courtney obtained a graduate degree in theoretical physical chemistry from UC Berkeley. She then attended law school at the University of Michigan, graduating summa cum laude. She also undertook several clerkships and served as a law professor before dedicating herself to writing full-time. Milan is represented by Kristin Nelson.

Courtney pens a weekly newsletter about tea, books, and a variety of other topics. She is known for her works that often feature carriages and corsets, reflecting her fascination with history and historical settings.
