The present invention provides a method for producing a modified conjugated diene polymer suitable for preparation of a polymer composition excellent in fuel economy. A conjugated diene polymer having a monomer unit based on a conjugated diene compound and a monomer unit based on a compound represented by the following formula (1) is reacted with an organometallic compound. The present invention relates to a method for producing a modified conjugated diene polymer in which a reaction product is reacted with a hydrocarbyloxysilane compound. (In the formula (1), R 11 , R 12 , R 13 , R 14 and R 15 each represent a hydrogen atom or an alkyl group, and at least one of R 11 , R 12 , R 13 , R 14 and R 15 is An alkyl group, R 16 , R 17 and R 18 each represent a hydrogen atom or a hydrocarbyl group, R 19 represents a hydrocarbylene group, and k represents 0 or 1).
