Fins are used to stabilize a rocket, so that it does not veer off course or tumble. However, most larger rockets do not use fins because of the atmospheric drag they create.

Do rockets have wing?
A rocket is a form of propulsion. If a rocket is used to power an airplane, it is referred to as a rocket-plane, and has wings like an airplane.

Sometimes fins are used to stabilize or guide a rocket in flight, but these are referred to as fins rather than wings.
