EX Delta Species (Japanese: Holon Research Tower) is the name given to the first expansion of cards of the Delta Species era of the Trading Card Game. It is also the eleventh EX Series expansion.

In Japan, Holon Research Tower was released after Mirage Forest; however, due to a translation issue, the sets' releases were switched in English-language territories, causing the set to be released in North America and the United Kingdom just three days after its release in Japan. However, due to Pokémon Organized Play's prereleases, for the first time in the history of the TCG, the entire set was available in English before it was in Japanese.

The set introduces the Holon Research Tower, located in the middle of the Mirage Forest (which was introduced in EX Legend Maker, hence why it was to be released before Delta Species); it is the home of scientists who conduct research on Mew and strange new Pokémon. These Pokémon have been altered by a wave of electromagnetic radiation produced by an experiment gone awry at Holon labs. The result is a new species of Pokémon called the Delta Species, symbolized by the lower-case delta (δ).

This set contains only 3 Pokémon-ex, a record low for any set in the EX series. The secret box topper card for this set is Azumarill.

The prerelease card for this set is Metang δ.
