The present invention relates to a composition for producing an N-vinylcarboxylic acid amide, the composition including (A) an N-(1-alkoxyethyl)carboxylic acid amide and (B) a carboxylic acid amide other than the N-(1-alkoxyethyl)carboxylic acid amide and the N-vinylcarboxylic acid amide, and satisfying the following conditions (1) to (4): (1) the composition has a melting point of 0 to 30° C.; (2) a water content is 0 to 1.00% by mass in a total amount of the composition; (3) a content ratio of the component (A) to the component (B) is 4.0 to 20.0 in terms of a molar ratio; and (4) a 5% by mass aqueous solution of the composition has a pH of 4.0 to 8.0. The present invention also relates to a method for producing an N-vinylcarboxylic acid amide, the method including thermally decomposing or catalytically decomposing the composition for producing an N-vinylcarboxylic acid amide.
