Yugo (Japanese: 勇午, Hepburn: Yūgo) is a Japanese manga series written by Shinji Makari [ja] and illustrated by Shū Akana. It was serialized in Kodansha's Monthly Afternoon magazine from December 1993 to July 2004, with its chapters collected in 22 tankōbon volumes. The series was transferred to Evening magazine that same year with the subtitle "the Negotiator" added in, where it was serialized until November 2015. Subsequent compilations of the original manga series also include this subtitle. An anime television series adaptation produced by G&G Direction and Artland aired from February to May 2004, comprising the manga's first two major story arcs within 13 episodes.

The story follows Yugo Beppu, a hostage negotiator, in various cases around the world. Having both a very tough body and determination, and his keen insight, Yugo often goes to great lengths to rescue those he is tasked to, without resorting to physical violence.

Theron Martin from Anime News Network elected the main character of the series Yugo Beppu as the "Best New Hero/Heroine" along with Kei Kurono of Gantz and Pacifica of Scrapped Princess. Martin declared he is "the most original hero: he deals with 'opponents' though his attention to understanding them and the sometimes-extreme actions he undertakes so that he can negotiate with them on their terms. A very slick, and very tough, individual."
