Cook Inlet (Dena'ina: Tikahtnu) stretches 180 miles (290 km) from the Gulf of Alaska to Anchorage in south-central Alaska. Cook Inlet branches into the Knik Arm and Turnagain Arm at its northern end, almost surrounding Anchorage. On its south end merges with Shelikof Strait, Stevenson Entrance, Kennedy Entrance and Chugach Passage.

The watershed covers about 100,000 km² of southern Alaska, east of the Aleutian Range, south and east of the Alaska Range, receiving water from its tributaries the Knik River, the Little Susitna River, and the Susitna and Matanuska rivers. The watershed includes the drainage areas of Denali (formerly named Mount McKinley). Within the watershed there are several national parks and the active volcano Mount Redoubt, along with three other historically active volcanoes. Cook Inlet provides navigable access to the port of Anchorage at the northern end, and to the smaller Homer port further south. Before the growth of Anchorage, Knik was the destination for most marine traffic in upper Cook Inlet. Approximately 400,000 people live within the Cook Inlet watershed.
The Cook Inlet region contains active volcanoes, including Augustine Volcano and Mount Redoubt. Volcanic eruptions in the region have been associated with earthquakes and tsunamis, and debris avalanches have resulted in tsunamis also. There was an earthquake of the magnitude of 7.1 on December 31, 1901 generated by an eruption that caused several tsunamis. In 2009 a lahar from Mt. Redoubt threatened the Drift River oil terminal.
The inlet was first explored and settled by Dena'ina people. In the 18th century, Russian fur hunters (promyshlenniki) were among the first European visitors. The Lebedev Lastochkin Company leader Stepan Zaikov established a post at the mouth of the Kenai River, Fort Nikolaev, in 1786. These fur trappers used Siberian Native and Alaska Native people, particularly Aleuts from the Aleutian Islands and Koniag natives from Kodiak, to hunt for sea otters and other marine mammal species for trade with China via Russia's then-exclusive inland port of trade at Kiakhta.
Other Europeans to visit Cook Inlet include the 1778 expedition of James Cook, its namesake, who sailed into it while searching for the Northwest Passage. Cook received maps of Alaska, the Aleutians, and Kamchatka during a visit with Russian fur trader Gerasim Izmailov in Unalaska, and combined these maps with those of his expedition to create the first Mercator projection of the North Pacific. The inlet was named after Cook in 1794 by George Vancouver, who had served under Cook in 1778. Turnagain Arm was named by William Bligh of HMS Bounty fame. Bligh served as Cook's Sailing Master on his 3rd and final voyage, the aim of which was discovery of the Northwest Passage.
Upon reaching the head of Cook Inlet, Bligh was of the opinion that both Knik Arm and Turnagain Arm were the mouths of rivers and not the opening to the Northwest Passage. Under Cook's orders Bligh organized a party to travel up Knik Arm, which quickly returned to report Knik Arm indeed led only to a river.
Afterwards a second party was dispatched up Turnagain Arm and it too returned to report only a river lay ahead. As a result of this frustration the second body of water was given the disingenuous name "Turn Again". Early maps label Turnagain Arm as the "Turnagain River".
The S.S. Farallon was a wooden Alaskan Steamship Company liner that struck Black Reef in the Cook Inlet on January 5, 1910. All thirty-eight men on board survived, and were rescued twenty-nine days later. Few white people visited upper Cook Inlet until construction of the Alaska Railroad along the eastern shores of Turnagain Arm and Knik Arm of Cook Inlet around 1915. The natives of the Eklutna village are the descendants of the residents of eight native villages around upper Cook Inlet.
During the 1964 Alaska earthquake, areas around the head of Turnagain Arm near Girdwood and Portage dropped as much as 8 feet (2.4 m) by subsidence and subsequent tidal action. Both hamlets were destroyed. Girdwood was later relocated inland and Portage was abandoned. About 20 miles (32 km) of the Seward Highway sank below the high-water mark of Turnagain Arm; the highway and its bridges were raised and rebuilt in 1964–66.
Most of Alaska's population surrounds Cook Inlet, concentrated in the Anchorage, Alaska area and in communities on the Kenai Peninsula. The more remote west side of the inlet is not connected to the road system, and is home to the village of Tyonek, Alaska, and a number of oil camps.
The Cook inlet Beluga whale is a genetically distinct and geographically isolated stock. The population has fallen to 278 in 2005 and they are listed as Critically Endangered in the IUCN Red List of Threatened Species. Perhaps due to local hunt, although though a recent article in the Anchorage Daily News questioned this conclusion.
Cook Inlet activities include commercial fishing, oil and gas development, release of treated sewage, noise from aircraft and ships, shipping traffic, and tourism. However, it is not known what impact these activities had on the beluga whale population.
In 2000, the US National Marine Fisheries Service listed the Cook Inlet beluga whale population as depleted and began development of a conservation plan. On October 22, 2008 the Cook Inlet beluga whale was put onto the endangered species list.
The Coastal Marine Institute at the University of Alaska Fairbanks's School of Fisheries and Ocean Sciences working with the U.S. Department of the Interior's Minerals Management Service (MMS), began a three-year project in 2003 focusing on the water circulation in Cook Inlet.
