One Island (Japanese: 1のしま Island 1), commonly referred to by fans as Knot Island (Japanese: むすびじま Bond Island), is the first island in the Sevii Islands archipelago. It is the most northwest of all the islands.

One Island is an isolated little place, and most of the younger people living on the island are eager to leave for big cities.

One Island is home to the Pokémon Network Center, run by Celio. The Net Center is located in the town of One Island, on the south side of the island. The Pokémon Net Center has a large, long-distance trade machine that enables Trainers to trade Pokémon with others in the Hoenn and Orre regions.

A small area extends to an island south of the town, called Treasure Beach, where valuable items, such as Big Pearls and Stardust, wash up and regenerate.

There is an enormous volcano, Mt. Ember, at the very north tip of the island, and it is reachable via a path known as Kindle Road, which is popular for its hot springs. The hot springs on Kindle Road can restore energy and vitality to Pokémon.

Mt. Ember makes the island a popular tourist spot thanks to the hot springs and climate. Luckily, Mt. Ember has not erupted in years.

Although believed to be inactive, the tunnels beneath the volcano are still warm with geothermic energy that attracts Fire-type Pokémon. Additionally, the presence of a legendary Pokémon on Mt. Ember keeps the peak ablaze with flames at night.

Mt. Ember and One Island are home to Moltres in Pokémon FireRed and LeafGreen.

Celio only completes the Net Center after the main character in Pokémon FireRed or LeafGreen brings him both the Sapphire and the Ruby, found on Five Island and atop Mt. Ember, respectively.

One Island appeared in The Search for the Legend, where Ritchie arrived there on a ferry, along with a Trainer named Silver. Although the island had been evacuated due to the imminent eruption of Mt. Magma, Silver disembarked the ship when it briefly stopped there, prompting Ritchie to follow him. He learned that Silver had come to Mt. Magma in order to fulfill his childhood dream of battling Moltres. However, as they encountered Moltres at the summit of Mt. Magma, they found it in a weakened state. Butch and Cassidy, who had accompanied the two in disguise, attempted to capture Moltres, but were eventually defeated.

After Moltres restored its strength using the volcano's magma, Silver started battling it with his Salamence. However, the battle was interrupted when the predicted eruption of Mt. Magma started happening, forcing Ritchie and Silver to flee. Despite this setback, Silver was still determined to finish his battle with Moltres someday.

FireRed & LeafGreen arc

In Now You See Me..., Red, Blue, Green, and Bill all boarded the Seagallop to One Island. Green was travelling to reunite with her parents, who had relocated there. Just before the Seagallop docked, Green was attacked by an invisible Pokémon, which also trapped her parents in a black hole. Overcome by trauma following the incident, Green was taken to the Pokémon Network Center to recover. Meanwhile, Red and Blue encountered Ultima, who took both of them to Two Island to learn her ultimate moves in order to combat the unseen opponent better.

In Some Things Are Better Left Unown, the Seagallop ferried Ultima back to One Island on her request. It picked up Green, who had recovered enough and was escaping from a mob, and took her and Ultima to Five Island to reunite with Red.

In Going Green, Green was revealed to have visited One Island earlier in order to catch Moltres on Mt. Ember.
