A catalyst for olefin polymerization comprising (A) a solid catalyst component prepared by causing (a) a magnesium compound, (b) a tetravalent titanium halide compound, and (c) an electron donor compound to come in contact with each other, (B) an organoaluminum compound of the general formula R<SUP>1</SUP><SUB>p</SUB>AlQ<SUB>3-p</SUB>, and (C) an oligomer of an organosilicon compound of the following chemical formula; R<SUP>4</SUP>-(R<SUP>2</SUP>R<SUP>3</SUP>SiO)<SUB>m</SUB>-R<SUP>5 </SUP>can produce olefin polymers having higher stereoregularity and a broader molecular weight distribution in a higher yield than conventional catalysts.
