The invention discloses an ethene polymerization catalyst containing ferrocene pyrrylimine titanium, and a preparation method and application of the ethene polymerization catalyst containing ferrocene pyrrylimine titanium. The catalyst is synthesized through a series of reactions and by using aminoferrocene and pyrrole-2-formaldehyde or a derivative of the pyrrole-2-formaldehyde as raw materials. The ethene polymerization catalyst containing ferrocene pyrrylimine titanium prepared in the invention has good catalytic activity for ethene polymerization, polymerization products has narrow molecular weight distribution, and therefore the ethene polymerization catalyst containing ferrocene pyrrylimine titanium prepared in the invention is expected to become a novel ethene polymerization catalyst.
