List of rogue waves

This list of rogue waves compiles incidents of known and likely rogue waves – also known as freak waves, monster waves, killer waves, and extreme waves. These are dangerous and rare ocean surface waves that unexpectedly reach at least twice the height of the tallest waves around them, and are often described by witnesses as "walls of water". They occur in deep water, usually far out at sea, and are a threat even to capital ships , ocean liners and land structures such as lighthouses.

In addition to the incidents listed below, it has also been suggested that these types of waves may be responsible for the loss of several low-flying United States Coast Guard helicopters on search and rescue missions.
