What is the title of the English opening song for the original Pokémon TV series?

The English opening song for the original Pokémon TV series is “Pokémon Theme.”

The song was written by John Siegler and John Loeffler and performed by Jason Paige. Its best-known refrain, “Gotta catch ’em all,” became one of the most recognizable slogans associated with the Pokémon franchise. The song accompanied the opening sequence of the English dub’s early episodes.

“Pokémon Theme” is sometimes informally called “Gotta Catch ’Em All” because that lyric dominates the chorus. The official title, however, is “Pokémon Theme,” which is the answer used for the song’s published and credited identity.

The anime later received many different opening songs as its regions, casts, and story arcs changed. Those later themes should not be confused with the original English opening. The song remains especially associated with the first English-language Pokémon episodes and the series’ initial worldwide expansion.
