Depends on the type. Also somewhat depends on what you mean by "stall", since a stall isn't really an absolute thing but is actually progressive.
In a tailwheel plane doing a three-point landing, the answer is a pretty definite "yes". Of course in a wheel landing the answer is an equally definite "no" - the plane is very much still flying when the mains touch the runway.
In a high-wing tricycle plane, the answer is a definite "sort of". A nice landing in a Cessna is done with the stall horn sounding for the last second or two. However trying to land in a true stall attitude is a good recipe for a tail strike (guess how I know). And the stall horn sounds quite a bit before the wing actually stalls (obviously, or it wouldn't be of much use as a warning).
My experience of low-wing planes (Cirrus, Cherokee, Mooney) is that you want a flatter attitude than a stall - the plane is still flying at touchdown.
So I think the general answer is "it depends".
