What is the English title of the first season of the Pokémon anime?

The English title of the first season of the Pokémon anime is Pokémon: Indigo League.

The season follows Ash Ketchum as he travels through the Kanto region, beginning his journey with Pikachu and competing for Gym Badges. Misty and Brock become his earliest traveling companions, while Team Rocket repeatedly pursues Pikachu.

In Japan, the material originally aired simply as Pokémon, or Pocket Monsters. “Indigo League” became the familiar English-season title because the story builds toward the Pokémon League competition at Indigo Plateau.

Episode counts can cause confusion because the Japanese and English versions differ. The Japanese season contains 82 episodes, while the English version is commonly listed with 80 episodes because of localization and broadcast differences.
