Shin Takahashi is a Japanese manga artist born on September 8, 1967, in Shibetsu, Hokkaido. He originally used the kanji for his name, 高橋 真, before adopting the hiragana pen name 高橋しん. Takahashi has been active as a professional manga creator since the early 1990s and is best known for creating the series Saikano (also known as She, the Ultimate Weapon).

Takahashi made his debut as a full-time manga artist in 1990 after winning the 11th Spirits Award. His first major serialized work, Ii Hito, ran in Shogakukan's Big Comic Spirits magazine from 1993 to 1999. However, his international recognition came with Saikano, which was serialized in Big Comic Spirits from 1999 to 2001. This series blends romantic drama with science fiction, telling the story of a high school girl whose body has been transformed into a powerful biomechanical weapon amid an escalating war. The series was commercially successful, selling over two million copies in Japan alone.

The Saikano manga was adapted into a thirteen episode anime television series produced by Studio Gonzo, which aired in Japan in 2002. The series was later released in North America by Viz Media. Saikano also received a two episode original video animation sequel titled Saikano: Another Love Song in 2005, as well as a live action film adaptation in 2006. Beyond Saikano, Takahashi has created numerous other manga series, including Kimi no Kakera, which ran from 2002 to 2010, Hana to Oku-tan from 2007 to 2019, Yuki ni Tsubasa from 2011 to 2013, and Kanata Kakeru from 2016 to 2018. He has also contributed to anime projects as an original creator and character designer. For example, he provided the original character designs for the short anime Road to You: Kimi he to Tsuzuku Michi in 2017.

Takahashi's artistic style is characterized by simple designs with loose lines, often using light colors, though he is also capable of producing detailed and dark pages when the story demands it. He was an early adopter of computer graphics in manga production, incorporating digital tools into his workflow before many of his contemporaries. His works frequently explore themes of personal relationships, loss, human resilience, and emotional melodrama, often placing kind or pure characters into realistic, difficult, or gloomy worlds. The creator's personal background as a long distance runner in high school and college, including participating in the Hakone Ekiden relay race, has influenced several of his works, which feature characters involved in track and field. His professional studio and office are known as Shin Present.
