无线通用串行总线（Wireless Universal Serial Bus，正式缩写Wireless USB，通常缩写WUSB或无线USB）是一种的高带宽的短距离无线传输技术，将通用串行总线（USB）2.0的技术的速度和易用性和无线技术的便捷性结合起来。

无线通用串行总线的无线传输技术是基于WiMedia联盟（WiMedia Alliance）的超宽带（Ultra-WideBand）的无线广播技术。它能在3米范围内以480Mb/s作传输，并能在10米范围内以110Mb/s作传输。比外，它的运载频率十分广，可在3.1GHz至10.6GHz频率范围内使用。因此，在不同地区内使用基于无线通用串行总线相关技术的设备，能依照当地的法律而调整至合适、合法的频率，这样可使无线通用串行总线及其设备能在世界各地广泛应用。

Wireless USB is a short-range, high-bandwidth wireless radio communication protocol created by the Wireless USB Promoter Group which intends to further increase the availability of general USB-based technologies. It is maintained by the WiMedia Alliance and (as of 2009) the current revision is 1.0, which was approved in 2005. Wireless USB is sometimes abbreviated as "WUSB", although the USB Implementers Forum discouraged this practice and instead prefers to call the technology Certified Wireless USB to distinguish it from the competing UWB standard.
