Speed is a scalar. Velocity by definition is a vector as it contains both speed (length of the vector) and direction.

It depends on which definition of scalar you are using. It is not a scalar in the relativistic sense, since the value will change depending on your frame of reference. But it is a scalar in the sense that it is just a number, with no direction.
