No. Velocity is a vector quantity.

Explanation:

Velocity is speed plus direction, therefore it is a vector quantity. Speed is a scalar quantity, as it does not include direction.

In the diagram below, both cars have a speed of 25 m/s, but their velocities are opposite from each other. The car on the left has a negative velocity, meaning it is moving in a negative direction relative to the other car, which is moving in a positive direction.
