Taichi 'Tai' Kamiya (八神 太一 Yagami Taichi?) is the main protagonist in the anime and manga Digimon Adventure and Digimon Adventure tri.. He is a DigiDestined, partnered with Agumon, and the bearer of the Crest of Courage. He is the older brother of Kari Kamiya.

His appearance is based on Taichi Yagami, the human star of the Digimon Adventure V-Tamer 01 manga, who in turn was based on Kentarou Kamon from the C'mon Digimon: The capering monster BUN one-shot. The goggles he wears are a characteristic that would eventually become shared among the leaders of the various DigiDestined in Digimon.
