The RMS Queen Mary, a retired British ocean liner permanently docked in Long Beach, is widely regarded as one of the most haunted locations in the United States.Reports of paranormal activity date back decades and include unexplained footsteps, apparitions (notably the “Lady in White” and the ghost of a drowned sailor in the engine room), and mysterious sounds in Cabin B340, which is now available for overnight stays for ghost hunters. The Queen Mary continues to be the focus of paranormal investigations, is regularly featured on TV shows and YouTube channels, and is considered an active site for both ghost tours and independent exploration.
