The invention provides a ziegler-natta catalyst with a furan component and a preparation method thereof and belongs to the technical field of olefin polymerization. According to the ziegler-natta catalyst with the furan component, a furan compound is used as an electron donor, a magnesium compound is used as a carrier, and a titanium compound is used as an active component; the molar ratio of the titanium compound to the magnesium compound is 5-30:1, and the molar ratio of the electron donor to the magnesium compound is 1:2-12. The ziegler-natta catalyst prepared by the preparation method has better activity when applied to vinyl polymerization, the obtained polymer is good in performance, the particle conditions are good, and the fine powder content is low.
