A skyrocket is a type of firework that uses a solid-fuel rocket to rise quickly into the sky. At the apex of its ascent, it is usual for a variety of effects (stars, bangs, crackles, etc.) to be emitted. Sky rockets use various stabilisation techniques to ensure the flight follows a predictable course, often a long stick attached to the side of the motor, but also including spin-stabilisation or fins.
A common misconception about professional fireworks displays is that skyrockets are used to propel the pyrotechnic effects into the air. In reality, skyrockets are more widely used as a consumer item. Professional fireworks displays utilize mortars to fire aerial shells into the air, not rockets.

In the Philippines, Republic Act 7183 was enacted to regulate and to control the sale, distribution, manufacture and use of fireworks and firecrackers for public safety. According to the said law, skyrockets (known in the Philippines as kwitis) are legal and are designed to propel from 40–50 feet (12–15 m) before exploding. Despite being legal, it poses danger to those using it. In 2012, it was recorded that skyrockets were the second most harmful firecracker after piccolo.
In the United Kingdom firework rockets are sold by weight, e.g.: 4 oz (110 g), 8 oz (230 g), 1 lb. This is not the weight of the rocket itself, but rather of a lead sphere whose diameter matches that of the rocket motor, officially defined as "The weight of a lead sphere that is just supported by a tube that the rocket motor will just fit into."
