The Screaming Tunnel is a small limestone tunnel, running underneath what once was a Grand Trunk Railway line (now the Canadian National Railway), located in the northwest corner of Niagara Falls, Ontario, Canada.

The actual location of the attraction is just off Warner Road. Often thought to be a railway tunnel, it was actually constructed only as a drainage tunnel so that water could be removed from the farmlands.

This water would go underneath the Grand Trunk Railway and down to the valley below. Farmers used this tunnel to transport goods and animals safely underneath the busy railroad above. The tunnel, constructed in the 1800 to 1900's, is 16 feet (4.9 m) in height and 125 feet (38 m) long.

A local legend recounts that the tunnel is haunted by the ghost of a young girl, who was sexually assaulted inside the tunnel and the legend also recounts her body was burned to prevent any evidence from being found. All versions of these legends end with the girls’ screams filling up the tunnel as she was burning to death.

Another local legend recounts that the tunnel is haunted by the ghost of a young girl, who after escaping a nearby burning farm building with her clothing ablaze, died within its walls. Several other variants of the legend exist locally. One other version has the girl set on fire by her enraged father after he loses custody of his children through a nasty divorce and possibly committed suicide after killing her.

The tunnel was used as a set during the filming of David Cronenberg’s 1983 film adaptation of Stephen King’s horror novel The Dead Zone.
