Post Traumatic is the debut solo studio album by Linkin Park vocalist Mike Shinoda. Released on June 15, 2018 under Shinoda's own name instead of his Fort Minor moniker, it is his second studio album outside of Linkin Park after Fort Minor's The Rising Tied. The album was announced on March 29, 2018, along with the release of two songs to promote the album, "Crossing a Line" and "Nothing Makes Sense Anymore". "Crossing a Line" and "Make It Up as I Go" were issued to radio stations as the album's two official singles.

Shinoda himself served as the primary producer of the album but with additional production on a few tracks by BASECAMP, Andrew Dawson, and Boonn. Linkin Park guitarist Brad Delson, Blackbear, K.Flay, Deftones lead vocalist Chino Moreno, Machine Gun Kelly, Ross Golan, Kevin Hissink (Boonn), and Grandson helped write some songs, though most were written by Shinoda.

The album contains content Shinoda recorded mostly by himself but additional instruments were played by Linkin Park drummer Rob Bourdon, Darren King, and Boonn with the content having been written by Shinoda after the death of his Linkin Park bandmate Chester Bennington on July 20, 2017. The three songs from the Post Traumatic EP are included as the first three songs of this album. The album received mostly positive reviews from critics.

On January 25, 2018, Shinoda revealed his second project as a solo artist with the release of the Post Traumatic EP, consisting of three tracks focusing on his feelings after the death of his Linkin Park bandmate and longtime friend Chester Bennington, who died by suicide on July 20, 2017. Precisely because of the issues addressed in the songs, Shinoda decided to publish the album in his name, without using his previous pseudonym, Fort Minor.

In early March, he unexpectedly announced that he was working on a solo album, inviting fans to meet him that day in Los Angeles to hear a new song and to join a music video. The inviting fans' event was documented and featured on the music video of "Crossing a Line". The album was finally announced on March 29, which includes the three tracks on the EP, and according to a statement by Shinoda, "It's a journey out of grief and darkness, not into grief and darkness. If someone went through something like that, I hope you feel less alone. If it has not happened, I hope you feel grateful."

In May 2018, Shinoda unveiled the tracklist, which included collaborations with Blackbear, Grandson, K.Flay, Machine Gun Kelly, and Deftones frontman Chino Moreno.

Every song in the album has its own music video. All of the album's tracks were solely produced by Shinoda.

The album begins with the three songs released on the Post Traumatic EP as the "grieving or lamenting" segment of the album. As described by Shinoda in an interview with KROQ, the album "goes from Nine Inch Nails vibes to N.W.A vibes." Some of the music is dark and grieving music while other music is upbeat and about different subjects. In an interview with Vulture, Shinoda describes,
