The following is a list of fictional characters from the manga and anime franchise Fist of the North Star by Tetsuo Hara and Buronson. All characters are from the original manga unless otherwise noted.

Hokuto Shinken (北斗神拳, "Big Dipper Divine Fist") is an ancient martial art rooted in different fighting styles dating back 1,800 years ago from China. Its founder was Shuken of the ancient "Hokuto Sōke" ruling line, who combined his Hokuto Sōke no Ken and Seito Gekken to create Hokuto Shinken. This martial art makes use of the opponents' 708 Keiraku Hikō, also known as tsubo or pressure points. These pressure points destroy the enemy from within.

The protagonist of the series, Kenshiro is the youngest of the four Hokuto brothers and the chosen successor of Hokuto Shinken (北斗神拳 Big Dipper God Fist). This martial art makes use of the opponents' 708 Keiraku Hikō (経絡秘孔 Meridian Channel Hidden Points, also known as simply Hikō, tsubo or pressure points). These pressure points destroy the enemy from within. The Hikō can also be used to heal and even to revive the dead. While a normal fighter uses 30% of his natural abilities, a Hokuto Shin Ken successor knows how to utilize his remaining 70% using Tenryū Kokyū Hō (転龍呼吸法 Art of Dragon's Breathing). A Hokuto Shinken successor can also resist attacks on the pressure points with the Hikō Fūji (秘孔封じ, Pressure Point Sealing), copy techniques after witnessing them only once with Suieishin (水映心, Water Reflection Spirit) and use Tōki (闘気 Fighting Spirit), an expert user can often radiate Tōki from his own body as an aura (Tōki no Aura, or Fighting Spirit Aura) whilst focusing it for attacks. It can be used to launch ki-based attacks that can be used to strike targets (even tiny ones, like the Keiraku Hiko) at long range, or, to defend the user from attack. Hokuto Shin Ken follows the Isshi Sōden(一子相伝) tradition: it can only be passed down from one father to one son, and there can only be one successor at a time. Sons that do not succeed in becoming successor must never practice the art again, or risk having their memories erased or fists destroyed. The ultimate Hokuto Shin Ken technique is the Musō Tensei (無想転生, Nil-Thought Rebirth), which can only be performed by one who completely understands sadness. "Hokuto Shin Ken" is named after the asterism Hokuto Shichi Sei, which is the Japanese name as the Big Dipper. Hokuto Shinken was created by Kenshiro's and Hyoh's ancestor Shuken who combined Seito Gekken's (西斗月拳, West Dipper Lunar Fist) Keiraku Hikō with his Hokuto Sōke no Ken (北斗宗家の拳, North Dipper Head Family Fist, North Dipper Originator Fist).
