T-X (referred to as the Terminatrix in some appearances) is the name of a fictional character who appears in the Terminator franchise. The T-X model is a gynoid assassin with a human-female appearance. The character was introduced as the main antagonist in the 2003 film Terminator 3: Rise of the Machines, portrayed by Kristanna Loken. The T-X has the ability to assume the appearance of other characters; therefore, several other cast members occasionally portrayed the T-X throughout the film. This ability to shapeshift is similar to that of the T-1000, the main antagonist of Terminator 2: Judgment Day.

The T-X was designed in Stan Winston studios, where it was considered particularly challenging to design, as the script required a character capable of holding its own against the original Terminator. Originally, the T-X's endoskeleton was meant to convey an androgynous shape which would permit the android to assume the superficial traits of both men and women, though later designs veered on it being more feminine. The final, approved T-X design was done by Aaron Sims, who designed it entirely on computer through a mixture of Photoshop and 3D software. The T-X endoskeleton was painted chrome black, in order to differentiate it from the silver sheen of the T-850 endoskeleton. The T-X was also fitted with blue running lights, rather than the original's red. John Rosengrant later stated that the individual parts of the T-X endoskeleton were hard coated, sanded and polished through machines, resulting in a mathematically perfect model, unlike the endoskeleton in The Terminator, which was sculpted by hand and lacked symmetry.

The T-X is designed to not only terminate humans but also rogue Terminators reprogrammed by the Resistance, an "anti-terminator terminator" as stated by John Connor. It is a composite of the T-800 and T-1000, a solid endoskeleton covered with a liquid metal "mimetic polyalloy", allowing it to take the shape of any humanoid it touches. Because it is only coated in this material, it is possible to remove it from the endoskeleton using immensely strong magnetic force, such as that from a cyclic particle accelerator. Although the official novelization of Terminator 2 expanded the origin of the T-1000 and reveals it had onboard nanotechnology (and programmable memory) that was capable of scanning the molecular structure of anything the T-1000 touched, the T-X has a built-in supply of more advanced nanobots in its fingers, which it can inject into other machines (even a less-advanced android), giving it remote control. An onboard plasma reactor powers all of the T-X's systems.
