Throughout the world, ฤทธิ์ณรงค์ (ฤทธิ์ณรงค์ 
) is a rare principally male, but scarcely female first name. The first name ฤทธิ์ณรงค์ is habitual in South-eastern Asia, particularly Thailand, where it is a rare principally male, but very infrequently female name. Much less frequently, ฤทธิ์ณรงค์ is the last name as well as the forename.
