The neGcon ("neh-gee-con", from the Japanese "nejiru", "to twist") was a third-party controller for the PlayStation manufactured by Namco.

The neGcon was an unusual design in that the left and right halves of the controller were connected by a swivel joint and thus the halves could be twisted relative to each other. The full extent of this twist was available to the console as an analogue measurement.

Also unusual for its time were the buttons. The regular PlayStation controller of the time featured all-digital controls with a D-Pad on the left; R1, R2, L1, and L2 shoulder buttons; triangle, circle, square, and X buttons on the right; plus select and start buttons in the centre area of the controller. The neGcon removed the L2 and R2 buttons as well as the select button. The neGcon replaced the digital circle and triangle buttons with digital A and B buttons, and also replaced the R1 shoulder button with a digital R shoulder button. The neGcon featured the digital D-Pad as one area similar to competing console's controllers and unlike the plus-shaped configuration of the official PlayStation controller.
