帕塞伊克河（英语：Passaic River 英语发音：/pəˈseɪ.ɨk/ pə-SAY-ik）是美国新泽西州北部的一条河流，长约129公里。帕塞伊克河从其上游蜿蜒而下，流经新泽西州的沼泽、乡野与城郊，沿途汇入多条源自新泽西州北部的支流。在其下游，帕塞伊克河流经本州最为工业化和城市化的地区，包括纽华克的市中心。其下游河道在20世纪遭受了严重的工业废渣污染。2014年4月，美国国家环境保护局宣布了一项17亿美元的计划用于移除下游八英里河段内的淤积于河底的430万立方码的有毒泥浆。这被认为是美国在受污染最严重的河段所进行的规模最大的清污计划。

The Passaic River (/pəˈseɪ.ᵻk/ pə-SAY-ik) is a mature surface river, approximately 80 mi (129 km) long, in northern New Jersey in the United States. The river in its upper course flows in a highly circuitous route, meandering through the swamp lowlands between the ridge hills of rural and suburban northern New Jersey, called the Great Swamp, draining much of the northern portion of the state through its tributaries. In its lower portion, it flows through the most urbanized and industrialized areas of the state, including along downtown Newark. The lower river suffered from severe pollution and industrial abandonment in the 20th century. In April 2014, the U.S. Environmental Protection Agency announced a $1.7 billion plan to remove 4.3 million cubic yards of toxic mud from the bottom of lower eight miles of the river. It is considered one of the most polluted stretches of water in the nation and the project one of the largest clean-ups ever undertaken.
