Ink Master: Turf War is the thirteenth season of the tattoo reality competition Ink Master that premiered on Paramount Network on January 7 and ended on April 14, 2020 with a total of fifteen episodes. The show is hosted and judged by Jane's Addiction guitarist Dave Navarro, with accomplished tattoo artists Chris Núñez and Oliver Peck serving as series regular judges. The winner was to receive $100,000, a feature in Inked magazine and the title of Ink Master. Due to the COVID-19 pandemic in the United States, the live finale was cancelled and no winner was announced for this season.

The premise of this season was having four teams based on their respective home region with each region being led by an Ink Master veteran.

This season saw the return of four veterans; season 10 contestants Jason Elliott and Frank Ready and season 11 contestants Angel Rose and Jimmy Snaz.

There was no winner for the thirteenth season of Ink Master, due to the COVID-19 pandemic. The three finalists (Bob Jones, Angel Rose and Jimmy Snaz) were awarded an undisclosed value monetary prize instead. The master canvases were revealed on YouTube Live.

The judging panel is a table of three or more primary judges in addition to the coaches. The judges make their final decision by voting to see who had best tattoo of the day, and who goes home.

The artist who wins best tattoo of the day gives his/her respective team and another team the power to put up one artist for elimination.

Each of the three judges can give a pardon to any eliminated artist of their choosing so that they may return to the competition after being eliminated.

Names, experience, and cities stated are at time of filming.
