Stellar Crown and its Japanese equivalent set Stellar Miracle make up the seventh expansion of cards for the Japanese Scarlet & Violet Era of the Pokémon Trading Card Game. This expansion mainly focuses on Tera or Terastallized Pokémon (with Terapagos as the main featured Pokémon), as well as various other Pokémon, characters and settings associated with The Indigo Disk, the second part of The Hidden Treasure of Area Zero DLC for the Pokémon Scarlet and Violet video games.

As the set's name implies, Stellar Crown debuts Terastallized Pokémon ex with the Stellar type for the first time in the TCG, known as Stellar Tera Pokémon ex. Cards of Stellar Tera Pokémon ex have several unique distinctions: they all have TCG types that follow the Pokémon's usual typing, as well as a uniquely powerful attack that is named after gemstones and requires three different types of Energy to use. To this end, this set also introduces Trainer cards which ease these Energy requirements, such as letting the player attach an extra Energy card in a turn, or reducing the Energy requirements for attacks used by Tera Pokémon.

Stellar Crown includes cards from the Japanese Stellar Miracle expansion and the Pokémon Card Game Battle Academy Deck Kit. Stellar Crown contains three ACE SPEC Trainer cards, 10 Pokémon ex, four Stellar Tera Pokémon ex, 13 illustration rare Pokémon, 11 ultra rare full-art etched Pokémon ex and Supporter cards, six special illustration rare Pokémon and Supporter cards and three hyper rare gold etched cards.

Stellar Crown is available in English, German, French, Italian, Spanish and Portuguese. Stellar Miracle was released in Japanese on July 19, 2024, followed by localized releases in Traditional Chinese on August 2, 2024. The Thai and Indonesian set equivalent, Stellar Guidance, was released on August 30, 2024 and September 20, 2024 in the respective regions.

The Japanese release of Stellar Miracle accompanied by the release of the Stellar Miracle Deck Build Box. The Traditional Chinese release was accompanied with the releases of the Pokémon Horizons: The Series Special Card Set (Traditional Chinese: 特別卡組 寶可夢地平線：系列 Special Card Set Pokémon Horizons: The Series), which includes 10 booster packs of Stellar Miracle and 3 promo cards featuring characters from Pokémon Horizons: The Series; and the Stellar Miracle Collector's Set (Traditional Chinese: 星晶奇跡 收藏家組合 Star Crystal Miracle Collector's Set), a product similar to the Collector's Set of the previous Transformation Mask expansion, which features 10 booster packs, a card list booklet and a Full Art promo card of Zeraora.
