W-CDMA (Wideband Code Division Multiple Access) is a wideband spread-spectrum channel access method that utilizes the direct-sequence spread spectrum method of asynchronous code division multiple access to achieve higher speeds and support more users compared to most time division multiple access (TDMA) schemes used today.

The term "W-CDMA" is also used to refer to the standard data interface used by the UMTS mobile communication system, W-CDMA (UMTS).
