"Poison: Iitai Koto mo Ienai Konna Yo no Naka wa" (Japanese: POISON 〜言いたい事も言えないこんな世の中は〜, lit. "Poison: In This World You Don't Say What You Want to Say")^[a] is a song by Japanese actor and singer Takashi Sorimachi from his second studio album, High Life (1998). It was written as the main theme to the drama series GTO, starring Sorimachi as the schoolteacher Eikichi Onizuka. Produced by Ken Yoshida [ja] and composed by Jinjirō Inoue [ja] with Sorimachi in charge of lyrics and vocals, "Poison" is a rock and J-pop track written in E major with an allegro tempo. The song was released as Sorimachi's fourth single on July 29, 1998, carrying the Mercury Music Entertainment label.

Upon release, "Poison" entered at No. 9 on Oricon's Singles Chart, and went on to chart in the top 20 for nine weeks. By the end of 1998, the single had surpassed 250,000 sales, taking No. 88 on Oricon's year-end chart and earning a Gold certification from the Recording Industry Association of Japan (RIAJ). A renewed single, titled the Movie Mix, was released on December 18, 1999, and peaked at No. 38 on Oricon's chart.

Post-release, "Poison" has appeared alongside various GTO projects and has been called representative of Sorimachi. In 2018, the song became an Internet phenomenon for its ability to soothe crying babies, attributed by academics to a rise and fall of a sound in the song, particularly during a guitar riff in the intro. This renewed attention caused the song to debut at No. 38 on Billboard Japan's Hot 100 chart, established in 2008. "Poison" has received two subsequent Gold certifications from the RIAJ: one in 2014 for 100,000 digital downloads, and another in 2023 for 50 million streams.
