Marie Louise Hartman (born March 11, 1959), known professionally as Nina Hartley,[1][2][3] is an American pornographic film actress and sex educator.

[19] Hartley sought a career in pornography as a way to make a living by having sex,[5] later telling Las Vegas Weekly, "Porn gave me easy access to women without having to date them or have a relationship.

[21][10][time needed] In 1982, during her sophomore year of nursing school, Hartley started working as a stripper at the Sutter Cinema and then the Mitchell Brothers O'Farrell Theatre.

[22][15] She told an interviewer that she chose the name "Nina" because it was easy for Japanese tourists to say during the time she was a dancer in San Francisco, and "Hartley" because it was close to her own last name, and she "wanted a name that sounded like that of a real person.

[27] She played the part of Hillary Clinton in the 2008 satirical pornographic film Who's Nailin' Paylin?,[13] with Lisa Ann in the role of Sarah Palin.

[37] She has said: Based on my experience as a woman and a sexual being, and my understanding that I had the right to decide for myself what to do with my life – that’s what I understood to be feminist, to give everybody choices – I didn’t choose to be a mother but I chose this [porn] because it suits me.

[38] Hartley has also been involved in socialist activism[39] and has also been affiliated with the Adult Performer Advocacy Committee (APAC), a labor union founded in 2014 for pornographic film actors.

[14] Library Journal called the book a "well-written guide" that is "strong on both safe sex and a permissive approach", saying Hartley "handles the material frankly, accurately, and with sensitivity".

[44] Following her divorce in 2003,[22] Hartley married Ira Levine, known professionally as Ernest Greene,[44] a director of bondage films and editor of Hustler's Taboo magazine, with whom she had had a secret relationship in the 1980s.
