Bowser's Castle (or simply Bowser Castle) is a recurring location in the Mario franchise. It is the domicile of Bowser and the base of operations for his army, the Koopa Troop. The castle's name, design, and greater location can differ between its appearances, but the castle is usually situated in a volcanic world. It is characteristically an important base from which Bowser formulates his plans and summons the Koopa Troop to take over the Mushroom Kingdom and kidnap Princess Peach. Many Super Mario series titles feature Bowser's Castle as the final location that Mario and his friends must visit to defeat Bowser and rescue Peach.

Bowser's Castle made its first overall appearance in Super Mario Bros., and its first Square Enix-related appearance is in Super Mario RPG: Legend of the Seven Stars, with the name Bowser's Keep. In Mario spinoff titles and crossover appearances, Bowser's Castle usually serves a purpose relating to the sport or theme of that game, such as a race course in the Mario Kart series.

In Super Mario RPG: Legend of the Seven Stars, Bowser's Keep is isolated on a mountain of red, jagged rocks, where is sits atop the largest rock, which resembles Bowser himself. Bowser's Keep can only be accessed by a long bridge that connects to the faraway Vista Hill. The halls of Bowser's Keep are lined with statues of an unidentified Koopa species. The castle is originally guarded by Terrapin soldiers. At the very beginning of the game during a standard princess-rescue, Mario goes through an entry room, a heavily guarded hallway, and a lava-filled room with bridges (the second of which collapses, being later replaced with Donut Lifts, before battling Bowser atop a chandelier in a large room.

The rescue is interrupted by the gigantic sword Exor crashing into the keep, scattering everyone inside. Exor destroys the bridge and proclaims the keep the new base of the Smithy Gang in Mario's world. Since Exor is the gateway to Smithy's dimension, the soldiers of the Smithy Gang have an easy time taking control of the castle. In fact, many of Bowser's soldiers defect or run away instead of fighting.

Eventually, Mario and company make it back to the keep using the Royal Bus from Nimbus Land. After traveling through the original rooms, now full of stronger versions of early-game enemies, such as Terra Cottas, Gu Goombas, and Malakoopas, intermixed with some larger enemies. After passing through the room where Mario and Bowser fought in the beginning, they travel through a dark, twisted hall and meet up with the thief Croco, who offers to sell them items. Following this is a challenge of six doors known as the Trial Course. After four of the six are completed, they fall from a doorway into a tall room and get into a battle against the brainwashed Magikoopa. After being defeated and freed from his mind control, Magikoopa creates a magic treasure box and offers free healing, while a nearby Croco sells better items than before. The next room is a long hall filled with Thwomps (including a large one), while Blazers are shot from off-screen and lead to battle against Big Berthas if touched. The final room is a copy of the Bowser fight room, and is held by Boomer. Once Boomer is defeated, the group is taken to the roof, where they battle Exor.

In the epilogue, the castle is shown being repaired by the reestablished Koopa Troop.
