The Only Girl in the Orchestra is a 2023 American musical short documentary film directed by Molly O'Brien.

[3] Orin O'Brien, a trailblazing double bassist, became the New York Philharmonic's first female musician in 1966, hired by Leonard Bernstein.

Now 87 and recently retired, she reflects on her remarkable career, valuing a quiet, supportive role for loved ones and students.

The documentary by her niece, Molly O’Brien, highlights Orin’s impact and her belief that fulfillment lies in embracing a secondary role.

[9][10] Paul Emmanuel Enicola reviewing the film at DOC NYC graded it A- and wrote, "Delightfully insightful and criminally short, The Only Girl in the Orchestra serves as a masterclass not only on how to make it in music; but also how to succeed in life.
