The Vauxhall Velox is a six-cylinder automobile which was produced by Vauxhall from 1948 to 1965. The Velox was a large family car, directly competing in the UK with the contemporary six-cylinder Ford Zephyr, and to a slightly lesser extent, with the A90, A95, and A110 Austin Westminster models.

It was introduced by Vauxhall shortly before the London Motor Show in October 1948,[1] as a successor to the Vauxhall Fourteen. Between 1948 and 1957 the Velox shared its body with the less-powerful four-cylinder Vauxhall Wyvern. From August 1954 through to October 1965, it shared its body with the more luxuriously-equipped Vauxhall Cresta, a tradition that ended with the introduction of the new PC Vauxhalls. The Velox name was discontinued at that time in favour of the more upmarket Cresta name, while a new flagship model, the Viscount, was launched.

The Velox and its Opel contemporaries are remembered for having mirrored North American styling trends much more closely than other European models of the time. That was particularly apparent following the 1957 introduction of the PA version of the Velox.
