哈德逊河（英语：Hudson River）是美国纽约州的大河，长507公里，上游分出莫华克河，西接伊利运河，末端导入纽约港，是纽约州的经济命脉。自北向南，流经纽约州东部。流经纽约市、奥尔巴尼市。下游为纽约州和新泽西州的边界。

哈德逊河又名赫逊河，由意大利探险家乔瓦尼·达韦拉扎诺于1524年发现，达韦拉扎诺因此而闻名于世。河流名称来源于英国探险家亨利·哈德逊。

哈德逊河下游实际上是潮汐型河口，潮汐甚至能够影响到特洛伊的“联邦水坝”处，大潮甚至可令纽约港部分地区难以航行。冬季，哈德逊河的浮冰因为潮汐的缘故或南或北地流动。哈德逊河在美洲印第安语中名为“Muhheakantuck”，意思是“两向流动的河”，这体现了哈德逊河的河口特性。哈德逊河的正式源头是“云之泪”湖。

The Hudson River is a 315-mile (507 km) river that flows from north to south primarily through eastern New York in the United States. The river originates in the Adirondack Mountains of Upstate New York, flows through the Hudson Valley, and eventually drains into the Atlantic Ocean, between New York City and Jersey City. The river serves as a political boundary between the states of New Jersey and New York, and further north between New York counties. The lower half of the river is a tidal estuary occupying the Hudson Fjord, which formed during the most recent period of North American glaciation, estimated at 26,000 to 13,300 years ago. Tidal waters influence the Hudson's flow from as far north as Troy.
