Sierra Madre

 is a location in Fallout: New Vegas, added by the DLC, Dead Money. The Cloud is a key location within Sierra Madre, and at its heart lies the pristine Sierra Madre Casino.

It is currently unclear which real-world location this corresponds to. Sierra Madre, CA seems a likely candidate as it would be within NCR territory, and can be reached by following the I-15 southwest from the Mojave Outpost until you reach the outskirts of the Boneyard. However, the book on which the 'Dead Money' DLC is based takes place in one of the many mountain ranges of Mexico known as the "Sierra Madre".
