Horizon Lines, Inc. was an American domestic ocean shipping and logistics company headquartered in Charlotte, North Carolina.

It was the largest Jones Act-compliant maritime shipping and logistics company, and accounted for approximately 37 per cent of all U.S. container shipments linking the continental United States to Alaska, Hawaii and Puerto Rico.

In the world fleet container ships go to the scrap yard at age 28 while Horizon still maintained C6 and C7 Lancer Class steam powered vessels.

[11][12] The reduction was attributed to pressure from bondholders and the possibility that Horizon would declare bankruptcy after losing a contract with Danish shipping group Maersk Line.

[citation needed] In November 2011, the company agreed to settle with the remaining shippers who opted out of the "Puerto Rico direct purchaser antitrust class action settlement" for $13.75 million [14] On 28 January 2012, the company reached an agreement with the U.S. Department of Justice to plead guilty to two counts of providing falsified oil record-keeping documents from a vessel in the U.S. West Coast-Hawaii service.

Alaska operations were bought by Matson, Inc.[16] for $469 million while, following regulatory approval, its Hawaii trade-lane business was acquired by The Pasha Group.
