Bayway Refinery is a refining facility in the Port of New York and New Jersey, owned by Phillips 66. Located in Linden and Elizabeth, New Jersey, and bisected by Morses Creek, it is the northernmost refinery on the East Coast of the United States. The oil refinery converts crude oil (supplied by tanker ships from the North Sea, Canada and West Africa and by rail from the Bakken Formation in North Dakota) into gasoline, diesel fuel, jet fuel, propane and heating oil. As of 2007, the facility processed approximately 238,000 bbl/d (37,800 m³/d) of crude oil, producing 145,000 bbl/d (23,100 m³/d) of gasoline and 110,000 bbl/d (17,000 m³/d) of distillates. Its products are delivered to East Coast customers via pipeline transport, barges, railcars and tank trucks.

The facility also houses a petrochemical plant which produces lubricants and additives and a polypropylene plant that produces over 775 million pounds of polypropylene per year. The refinery has its own railway container terminal and heliport.

The workers at the plant have been unionized under the International Brotherhood of Teamsters (Local No. 877) since 1960.

The refinery has had and continues to have environmental issues, culminating in the major $225 million Exxon Mobil-New Jersey Environmental Contamination settlement. A 2010 investigative report conducted by WABC-TV, the ABC flagship station in New York City, characterizes the Bayway Refinery as a "repeat offender" of environmental regulations.
