Nihon No Don（日本的首领, 大致翻译为《日本教父》或《日本老爷子》）是一部1977年至1978年上映的日本有组织犯罪电影三部曲。该系列非常松散地以日本最大的黑帮的真实事迹为基础，改编自记者笠原和夫的小说，由东井制作，他早些时候用深泽近治的《没有荣誉和人性的战斗》改写了黑帮类型的规则。

Nihon No Don (日本の首領, approximately translating as The Japanese Godfather or The Japanese Don) is a Japanese trilogy of organized crime films released from 1977 to 1978. Very loosely based on the real-life exploits of Japan's biggest yakuza gangs, the series was adapted from a novel by journalist Kazuo Kasahara and was produced by Toei, who earlier rewrote the rules of the yakuza genre with Kinji Fukasaku's Battles Without Honor and Humanity.
