Yu-Gi-Oh! Theme is the English opening theme to the Yu-Gi-Oh! anime series. It was composed by Wayne Sharpe. It debuted on September 29, 2001, and aired during episodes 1 to 49. It was replaced by the second Yu-Gi-Oh! theme in episode 50. It returned on May 1, 2004, in episode 122 and aired until the end of the series.
It was also used as the opening to the Yu-Gi-Oh! Capsule Monsters anime series.
