Hikaru no Go (??????, lit. "Hikaru's Go") is a manga series, a coming of age story based on the board game Go written by Yumi Hotta and illustrated by Takeshi Obata with an anime adaptation. The production of the series' Go games was supervised by Go professional Yukari Umezawa (5-dan). The manga is largely responsible for popularizing Go amongst the youth of Japan since its debut, and in other areas such as China, South Korea, and Taiwan. More recently it has gained much popularity in the United States. The title is sometimes abbreviated 'HnG'.

First released in Japan in Shueisha's Weekly Sh?nen Jump in 1998, Hikaru no Go achieved tremendous success, spawning a popular Go fad of almost unprecedented proportions; it received the Shogakukan Manga Award in 2000 and creators received Tezuka Osamu Cultural Prize in 2003 for the series. Twenty-three volumes of manga were published in Japan, comprising 189 chapters plus 11 "omake" (extra chapters). The anime series, which was created by Studio Pierrot, ran for 75 half hour episodes from 2001 to 2003 on TV Tokyo, along with the 77-minute extra New Year's Special that aired in January 2004.

In January 2004, the manga series debuted in the United States in the English language periodical Shonen Jump published by VIZ, now VIZ Media. In 2005 it was announced that VIZ Media also has the license to the anime. Hikaru no Go Volume 1 DVD was released on December 27, 2005. A Hikaru no Go "Sneak Preview" DVD (first episode) was released in the January 2006 issue of Shonen Jump (Volume 4, Issue 1) to subscribers. Hikaru no Go airs on ImaginAsian TV in the United States. It premiered on the online streaming service Toonami Jetstream on July 14, 2006. In the April 2008 issue of Shonen Jump, it was revealed that this was the last chapter to be published in the Shonen Jump magazine. So far 16 volumes of the graphic novels have been released in the US as of October 2009.
