Witching Hour is the third studio album by English electronic band Ladytron. It was released in the United Kingdom on 3 October 2005 by Island Records. A special edition of the album was released in 2007, containing a bonus disc of recent music videos and the documentary Once Upon a Time in the East: Ladytron in China, detailing highlights of their 2004 tour across China. "Sugar" and "Destroy Everything You Touch" were released as singles. Some versions of this album do not include "CMYK" or "Untitled".

With a modern literal meaning of "midnight," the term witching hour refers to the time of day when supernatural creatures such as witches, demons, and ghosts are thought to appear and to be at their most powerful and black magic to be most effective. It may be used to refer to any arbitrary time of bad luck or in which something bad has a greater likelihood to occur (e.g., a baby crying, a computer crashing, or stock market volatility).
