Leatherface is a 2017 American horror film directed by Julien Maury and Alexandre Bustillo, written by Seth M. Sherwood, and starring Stephen Dorff, Vanessa Grasse, Sam Strike, and Lili Taylor. It is the eighth installment in the Texas Chainsaw Massacre (TCM) franchise, and works as a prequel to The Texas Chain Saw Massacre (1974) and Texas Chainsaw 3D (2013), explaining the origin of the series' lead character.

It is the third and final installment of the Millenium Films' alternate continuity and chronologically the first of the alternate continuity.

Following the financial success of Texas Chainsaw 3D, a sequel went into development from director John Luessenhop for a planned shoot in Louisiana, but failed to receive the greenlight to move forward. In favor of avoiding the convoluted continuity of the previous films while going in an unexpected direction, Seth M. Sherwood pitched Leatherface to Millennium Films as a prequel that would follow the titular character in a mentally competent state, enduring trauma that transforms him into the intellectually disabled murderer seen in the previous films. Maury and Bustillo signed on as directors after reading the screenplay, impressed with what they found to be a unique take on the long-running franchise.

Principal photography commenced in Bulgaria in May and June 2015, with locations and sets chosen for their resemblance to the Texas terrain and as homage to the series' previous films. After being temporarily shelved by Lionsgate Films in 2016, the film was made exclusive via DirecTV on September 21, 2017, before receiving a wider release on video on demand and limited theaters, simultaneously, in North America on October 20, 2017. It received generally mixed reviews from film critics, and garnered $1,476,843 worldwide. Lionsgate and Millennium Films lost the rights to produce future Texas Chainsaw Massacre films because of its delay in release.
