''Esox lucius'' is found in fresh water throughout the Northern Hemisphere, including [[Russia]], [[Europe]], and [[North America]]. It has also been introduced to lakes in [[Morocco]], and is even found in brackish water of the [[Baltic Sea]], but they are confined to the low-salinity water at the surface of the sea, and are seldom seen in brackish water elsewhere.{{Citation needed|date=May 2011}}

Within North America, northern pike populations are found in [[Maine]], [[New Hampshire]], [[Vermont]], [[Massachusetts]], [[Rhode Island]], [[Connecticut]], [[New York (state)|New York]], [[New Jersey]], [[Pennsylvania]], [[Maryland]], [[West Virginia]], [[Ohio]], [[Michigan]], [[Indiana]], [[Illinois]], [[Wisconsin]], [[Minnesota]], [[Iowa]], [[Missouri]], [[North Dakota]], [[South Dakota]], [[Nebraska]], [[Kansas]], [[Montana]], [[Idaho]], [[Utah]], [[Colorado]], [[Oklahoma]], northern [[Texas]], northern [[New Mexico]], northern [[Arizona]], [[Alaska]], the [[Yukon]], the [[Northwest Territories]], [[Alberta]], [[Saskatchewan]], [[Manitoba]], [[Ontario]], and [[Québec]] (pike are rare in [[British Columbia]] and east coast provinces). Watersheds in which pike are found include the [[Ohio River|Ohio Valley]], the [[upper Mississippi River]] and its tributaries, and the [[Great Lakes Basin]]. They are also stocked in, or have been introduced to, some western lakes and reservoirs for sport fishing, although some fisheries managers believe this practice often threatens other species of fish such as [[Bass (fish)|bass]], [[trout]], and [[salmon]], causing government agencies to attempt to exterminate the pike by poisoning lakes, such as [[Stormy Lake, Alaska]].<ref>{{cite news
