An object of the present invention is to provide a process for efficiently producing an alkyl methacrylate. The present invention provides a process for producing an alkyl methacrylate comprising reacting carbon monoxide and an alcohol having 1 to 3 carbon atoms with methylacetylene in the presence of a catalyst comprising a Group 10 metal compound, a protonic acid and a phosphine compound, wherein the methylacetylene has a propadiene content of 50 ppm by weight or less, the use amount of the methylacetylene is 200000 mol or more based on 1 mol of the Group 10 metal compound, and the reaction is performed in the presence of water in an amount of 40000 mol or less based on 1 mol of the Group 10 metal compound.
