Curse of the Hidden Mirror is the thirteenth studio album by American rock band Blue Öyster Cult, released on June 5, 2001. The only single from the record was the poorly received "Pocket". Lackluster sales and poor relations led to the band being dropped by their label, Sanctuary Records; as a result, BÖC did not release another studio album for nearly 20 years, until the release of The Symbol Remains in 2020.
