Nippon Steel Yahata Soccer Club (新日本製鐵八幡サッカー部 Shin-Nihon Seitetsu Yahata Sakkā-Bu) was a Japanese football club based in Kitakyushu, Fukuoka Prefecture.

During the 1960s the club provided the Japan national football team with many quality players which strengthened the squad for the 1964 and 1968 Olympic tournaments.

Yahata Steel was one of the original eight clubs that founded the Japan Soccer League (JSL) in 1965 ("Original Eight"[a]), and building on its Emperor's Cup win in 1964, it was runner-up of the JSL to Toyo Industries (current Sanfrecce Hiroshima) in 1965 and 1966.

In 1981, however, after an uneventful decade in which the club did not win any honours nor was in danger of relegation, Nippon Steel was relegated to Division 2 and never played top flight football again.

The 1999 season was the last with Nippon Steel Yahata in the Kyushu league.
