The Japanese Metal Mine Workers' Union (, Hitetsu Rengo) was a trade union representing workers in the ore mining industry in Japan. The union was founded in 1964 as the Federation of Japanese Metal Resource Workers' Unions (Shigenroren), and affiliated to Japanese Confederation of Labour the following year. By 1967, it had 13,411 members. It was affiliated to the Japanese Trade Union Confederation from the late 1980s, and by 1996 had 23,500 members.
