Stephenson's Rocket was an early steam locomotive of 0-2-2 wheel arrangement.
It was built for, and won, the Rainhill Trials held by the Liverpool and Manchester Railway in October 1829 for demonstration of improved steam locomotive designs able to demonstrate fixed stationary engines would not be required.

Rocket  was designed by Robert Stephenson in 1829, and built at the Forth Street Works of his company in Newcastle upon Tyne.

Though Rocket was not the first steam locomotive, it was the first to bring together several innovations to produce the most advanced locomotive of its day.
It is the most famous example of an evolving design of locomotives by Stephenson that became the template for most steam engines in the following 150 years.

The locomotive was preserved and displayed in the Science Museum in London until 2018.
It was loaned to Newcastle Discovery Museum between 22 June and 9 September 2018, to the Science and Industry Museum in Manchester from 25 September 2018 to 8 September 2019, and moved to the National Railway Museum in York later in 2019.
