The record for the fastest spacecraft of all is held by the twin Helios probes that were placed in orbit around the Sun. Both these vehicles reached top speeds of around 150,000 mph (250,000 km/h) at closest approach to the Sun in their highly elliptical orbits, Helios 2 being marginally the swifter.

As the New Horizons launch approached, many news reports hailed the new probe as the fastest spacecraft ever. However, that is not quite correct. ... Helios 2 was slightly faster than its twin craft, and this probe still holds the speed record as not only the fastest spacecraft but also the fastest manmade object in history.

I believe Voyager 1 is the fastest spacecraft, the JPL website says it is travelling 3.6 AU per year (astronomical units). Other than our own sun, I think Bernard is the closest star, 5.9 light years away. If Voyager 1 was heading towards Bernard, at it's current speed, it would take just over 100,000 years to get there.
