The present invention addresses the problem of providing a method for producing an oxymethylene copolymer, which is capable of producing an oxymethylene copolymer having a high molecular weight with high yield and high economic efficiency. This problem is able to be solved by a method for producing an oxymethylene copolymer, in which a copolymer starting material containing a trioxane and a comonomer is subjected to a polymerization reaction in the presence of a polymerization initiator that contains an acidic compound (A), and wherein: the copolymer starting material contains a basic compound (B); an acidic compound (C) that is different from the acidic compound (A) is added into the copolymer starting material before performing the polymerization reaction, thereby causing a reaction between the basic compound (B) and the acidic compound (C) in advance; and the polymerization reaction is carried out by means of melt polymerization.
