Ring King is an arcade boxing game. It was published in 1985 by Data East in North America.

The game continues the series' theme of comical sports as the player takes the role of a boxer who makes his way from his debut to become a world champion. Ring King, though perhaps unintentionally, is standard of the boxing creations of its era, via providing quirky monikers for opponents the player encounters; in its arcade release, these number eight (8): Violence Jo (this entry level fighter is the champion, in the NES version), Brown Pants, White Wolf, Bomba Vern, Beat Brown, Blue Warker (reigning champion, in the arcade version), Green Hante and Onetta Yank. Assuming the player wins the championship, arcade play continues cycling through only the last of the afore-listed three (Blue Warker, Green Hante, Onetta Yank).
