W-VHS is a HDTV analog recording videocassette format created by JVC. The format was originally introduced in 1994 for use with Japan's Hi-Vision, an early analog high-definition television system.

W-VHS was named so because "W" in Japanese sounds like "double".

The recording medium of W-VHS is a ½-inch metallic magnetic tape stored in a cartridge the same size as VHS. The tape can be used to store 1035i (HD) or 480i (SD) and a double channel of 480i (for storing 3D programs)(SD2) analog signals (but not 480p, 720p or 1080i). The video signal is recorded using a method called "time compression integration" which "records separated component video, luminance and color signals offset by time in alternating parts of the video track". Because video signals are recorded in component form instead of the S-Video (Y/C) color under method used by S-VHS, standard definition image quality for W-VHS is typically much higher, due to the lack of noise caused by a chroma sub-carrier. Audio is stored in the VHS Hi-Fi or S-VHS Digital Audio formats.
