《胜利大决战》（V）最早是一出1983年于全国广播公司（NBC）首播、由肯尼斯·强森（Kenneth Johnson）编导的美国科幻电视迷你影集。它在1984年推出了一个续集，迷你影集《胜利大决战之最后战役》（V: The Final Battle），以及一季（1984-85）电视影集（原名也叫V，不过为了有所区分，有时候也叫它V: The Series）。各地在重播的时候，通常是将这三个作品接续播完，不特别区分名称。

V (also known as V: The Series) is a 60-minute (47 to 49 minutes without commercials) weekly television series that aired in the United States on NBC in 1984-85. It is a continuation of the science fiction franchise about an alien invasion of Earth by a carnivorous race of reptilians known as "The Visitors" which was originally conceived by American writer, producer, and director Kenneth Johnson. Johnson, however, was not involved in the production of the weekly series. At a cost of one million dollars per episode, V was the most expensive series to be produced for television.
