The speed of light varies depending on the medium the light is traveling through. In a vacuum however, which is the fastest medium in which light can travel, the speed of light is 299,792,458 m/s.

The speed of light in a vacuum (such as empty space) is 3.0 X 10^8 m/s.
In a dielectric the speed of light is v = c/n, where n is the index of refraction.
