We report herein a regio‐ and stereoselective photocatalytic hydrogenolysis of allylicalcohols to form unsaturated hydrocarbons employing a palladium(II)‐loaded titanium oxide; the reaction proceeds at room temperature under light irradiation without stoichiometric generation of salt wastes. Olefin and saturated alcohol moieties tolerated the reaction conditions. Hydrogen atoms were selectively incorporated
