The Eterna Historical Museum (Japanese: ハクタイ歴史博物館 Hakutai Historical Museum) is an anime-exclusive building located in Eterna City in Sinnoh. It appeared in A Secret Sphere of Influence, in which it was visited by Ash, Dawn, Brock, Nando, and Gardenia, the local Gym Leader.

Jessie, James, and Meowth were hired by Saturn, one of Team Galactic's Commanders, to steal the Adamant Orb. Although they managed to get a hold of the orb, they failed to escape the museum with it after the building was surrounded by policemen working under the orders of Officer Jenny.
In Losing Its Lustrous!, the Adamant Orb was being transported via a police plane to the Celestic Town Historical Research Center, where it would be studied along with the Lustrous Orb. However, it was stolen by Team Galactic, which intercepted the aircraft transporting the Adamant Orb.
Among the many artifacts inside the museum are a scale model of the Space-Time Towers and statues of Uxie, Mesprit, and Azelf. Inside the entrance gates, the museum is guarded by statues of the Legendary Dialga and Palkia.
