Martha Mills Noxon (born August 25, 1964) is an American television and film writer, director, and producer.

She is best known for her work as a screenwriter and executive producer on the supernatural drama series Buffy the Vampire Slayer (1997–2003).

Noxon would often accompany her father when he traveled to shoot documentary films and was already in love with the idea of movies.

[7] Although the industry at the time was all about the log line, which was very successful for writers like Joss Whedon, Noxon had to go through a process where she discarded that construct and got in touch with the vision that she felt connected to — and realised that all of the work she had been doing was in a vacuum.

[7][clarification needed] After the first season of episodes of Buffy the Vampire Slayer were produced, Noxon's agent encouraged her to watch them and try to take meetings and get on the show.

After watching the initial episodes, she realized she loved the show, but was already booked to work on The Pretender, which was picked up to air, so seemed like it was a more safe bet.

Noxon described her experience on Buffy as charmed, as The WB Network allowed the show creators to work with little interference.

[9] At the season's conclusion, fan reaction was mixed, leading some to criticize Whedon for abandoning creative control and stewardship of Buffy to Noxon.

In 2004, Noxon wrote and produced a pilot entitled Still Life for Fox about a family recovering from the death of their son, a police officer.

[12] In September 2006, Noxon joined the ABC medical drama Grey's Anatomy for its third season, as consulting producer.

[13] In February 2007, Noxon co-wrote the third-season Grey's Anatomy episode "Some Kind of Miracle" with series creator Shonda Rhimes.

[16] She won the WGA Award for Best Drama Series (after being nominated for the second consecutive year) at the February 2010 ceremony for her work on the third season of Mad Men.

[19] In 2014, Noxon, along with co-creator Sarah Gertrude Shapiro, began working on the Lifetime comedy-drama series UnREAL.

[20] Noxon is also one of the executive producers of the CBS medical drama series Code Black which premiered in the fall of 2015.

[30][31] Noxon is the creator, executive producer, and writer for the HBO 8-part miniseries Sharp Objects, adapted from Gillian Flynn's novel of the same name.

[32] The project was initially planned as a feature film, but Noxon convinced the network that the story would work better as a limited series.

[33] The show, which premiered on July 8, 2018, is directed by Big Little Lies director Jean-Marc Vallée and stars Amy Adams, Patricia Clarkson and Chris Messina.
