A reaction–diffusion problem with an obstacle potential is considered in a bounded domain of 
. Under the assumption that the obstacle 
is a closed convex and bounded subset of 
with smooth boundary or it is a closed n-dimensional simplex, we prove that the long-time behaviour of the solution semigroup associated with this problem can be described in terms of an exponential attractor. In particular, the latter means that the fractal dimension of the associated global attractor is also finite.
