In this paper we classify static plane symmetric spacetimes according totheir matter collineations. These have been studied for both cases when theenergy-momentum tensor is non-degenerate and also when it is degenerate. Itturns out that the non-degenerate case yields either {\it four}, {\it five},{\it six}, {\it seven} or {\it ten} independent matter collineations in which{\it four} are isometries and the rest are proper. There exists threeinteresting cases where the energy-momentum tensor is degenerate but the groupof matter collineations is finite-dimensional. The matter collineations inthese cases are either {\it four}, {\it six} or {\it tenComment: 15 pages, LaTex, no figure
