A method for producing a modified conjugated diene polymer usable as a raw material of a crosslinked polymer which is used for use in tires and the like of automobiles and can enhance low fuel consumption performance of automobiles and the like is provided. A method for producing a modified conjugated diene polymer comprising a polymerization step in which a monomer including a conjugated diene compound or a monomer including a conjugated diene compound and an aromatic vinyl compound is polymerized in the presence of at least one compound selected from the group consisting of the following formulae (1) and (2) and an alkali metal compound or an alkaline earth metal compound to obtain a modified conjugated diene polymer. (In the formulae, A1 is a hydrocarbylsilyl group in which three H's (hydrogen atoms) in a “—SiH3” structure are each substituted by a hydrocarbyl group, and R1 and R2 are hydrocarbylene groups.)
