The wonderful thing about Supernatural is that it attracts the kind of writer that has this vast love for genre and horror. People that come in to interview for this job who have this encyclopedia knowledge. We just sit and chew the shit for an hour about this sort of thing. It’s sort of like having coffee with geeky friends. – Sera Gamble, Comic Con 2011, Source

This section has entries for all the people who have had a writing credit on Supernatural. The Writer and Director Episode Guide lists each episode by director and writer.

The Supernatural writing team and post-production is based in LA while the show (except for 1.01 Pilot) is filmed in Vancouver.

Following a large roster of writers in season one (of which most were "freelancers"), Supernatural has had a core group of around eight writers each season. Writing on a TV show is not a solo effort -- story arcs and individual episodes will be developed and broken in collaboration with the writers' room. Eric Kripke, Bob Singer and Sera Gamble in particular have had a much greater input and influence on the scripts than their individual writing credits indicate. In addition story editors and writers assistants have input at different parts of the scripts development. Some writers assistants have gained writing credits on the show including Emily McLaughlin, Jenny Klein, Jackson Stewart and John Bring. Stunt coordinator Lou Bollo has also received a "story by" credit for two episodes.

It is normal practice for TV writers and directors to be given a producer or executive producer credit as they become more senior in the production team, although not all of these will actually take on roles more broadly involved in the show's production. Robert Singer, who has been co-showrunner (executive producer) since the beginning only has three episode writing credits, although he has input on all scripts. He stepped back from the executive producer role to consulting producer in season eleven, while still remaining one of the show's regular directors. With season twelve, Singer once again returned to the role as co-showrunner alongside Andrew Dabb.

Some regular writers who have moved on from Supernatural include:

Supernatural's meta commentary on writers took the form of Chuck Shurley who we meet in 4.18 The Monster at the End of This Book. His name Carver Edlund was a portmanteau of Jeremy Carver and Ben Edlund. (In the same episode writers Sera Gamble and Julie Siege appear in the form of the Publisher who was called Sera Seige in the script Source). Chuck is an author who wrote the Supernatural book series, and continued to write even though the books were no longer being published. Unbeknownst to him, the inspiration of the books was divine - as he is a prophet of God. At the end of season five, it is suggested that Chuck may in fact be God.

The metaphor is of the writer as creator. The character is an avatar for Kripke himself (Source) and is used to comment on the text and process of writing with reference to specific past episodes of the show. This metaphor would also hold then that God, the creator, was also the writer. We have a trinity here - Chuck, Kripke and God.

In 6.15 The French Mistake, Sera Gamble was portrayed as the new showrunner no-one would listen to, Bob Singer was the world weary producer/director and Eric Kripke was hoping to hit the big time with his new script Octacobra.
