The invention provides a novel titanium catalyst for polyester and a preparation method thereof. The novel titanium catalyst comprises the following components: titanate, complex ligands with different functionality degrees, a stabilizer, a solvent and a catalyst, wherein the mass percentage of titanium element is 0.1-20%, the molar ratio of difunctional ligands to trifunctional ligands to tetrafunctional ligands is (1-10):(0-5):(0-5), and the molar ratio of titanium atoms to the ligands in the solvent is (4:1)-(1:20). The titanium catalyst prepared by the method has excellent water resistance, and the catalyst can be dissolved in ethylene glycol and then can be conveniently added into a reaction system during industrial production. A polyester product polymerized by the titanium catalystprepared by the method has good color and luster, and is suitable for bottle-grade polyethylene terephthalate (PET) production with high requirements on color and luster.
