The present invention provides a method of producing 2,4,6-tris(hydroxyphenyl)-1,3,5-triazine compound in which no rapid solidification or the like occurs and generation of by-products is suppressed, thereby enabling to reduce decrease in the yield. Particularly, the present invention is a method of producing 2,4,6-tris(hydroxyphenyl)-1,3,5-triazine compound represented by the following Formula (1): wherein the reaction between cyanuric halide compound represented by the following Formula (2): and hydroxyphenyl compound represented by the following Formula (3): is carried out by using, as the reaction solvent, a solvent containing sulfolane as the main component in the presence of a Lewis acid at an amount of 0.3 to 0.7 equivalent with respect to 1 equivalent of halogen atom of the cyanuric halide compound represented by the Formula (2), or by using a mixed solvent of inert solvent and cycloalkyl alkyl ether represented by the following Formula (4): z1-0-z2  (4)
