Before the arrival of Europeans in Alaska, Ninilchik was a Dena'ina Athabaskan lodging area used for hunting and fishing. The name Ninilchik probably derives from Niqnilchint, a Deni'ana Athabaskan word meaning "lodge is built place".
The first people who would permanently stay in the village were Russian colonists who moved there from Kodiak Island in 1847 before the Alaska Purchase. They were Russian Grigorii Kvasnikov (Anglicized to Kvasnikoff), his Russian-Alutiiq wife Mavra Rastorguev (daughter of Agrafena of Afognak), and their children. Their dialect of Russian (plus a few words borrowed from Alaska Native languages) was the primary language spoken in Ninilchik long past the purchase of Russia's interests in Alaska by the U.S. in 1867. A few speakers of the Ninilchik Russian dialect are still alive in 2008, including one married couple who continues to speak the language to each other.
The 1880, United States Census listed 53 "Creoles" living in Ninilchik in nine extended families. All nine founding families of Ninilchik are descendants of the Kvasnikoffs and Alaska Natives.
In 1896, a school was built and staffed by Russian Orthodox priests and laymen. In 1901, the Russian Orthodox Church was redesigned and constructed at its current site. In 1911 the first school sanctioned by the U.S. government was started and early in 2011 the community celebrated its 100th anniversary of the Ninilchik School.
2007 Caribou Hills Fire 
A 2007 fire that burned near Ninilchik, known as the Caribou Hills Fire, moved toward the town and at its peak threatened approximately 300 structures. It eventually burned nearly 60,000 acres (240 km2) and destroyed 197 structures. For the main article, go to 2007 Caribou Hills fire.
Native Alaskans 
The Alaska Native Claims Settlement Act recognized Ninilchik as an Alaska Native village, which led to the formation of the Ninilchik Native Association Incorporated and eventually to the further recognition, by the US Congress, that Ninilchik's descendants comprised a quasi-sovereign government (equivalent to American Indian tribes), thereby establishing the Ninilchik Traditional Council (NTC) as the governing body for Natives who live in the area surrounding Ninilchik or who descended from the original inhabitants.
The original village is located at the mouth of the Ninilchik River. A small harbor has been constructed near the mouth of the river. The name "Ninilchik" is used today, however, to refer to the original village as well as the community that has grown up around it, extending several miles north, east, and south. Residents of Ninilchik sometimes refer to the original village as Ninilchik Village. Ninilchik as a town is not incorporated, but it is under the jurisdiction of the Kenai Peninsula Borough (KPB) and the State of Alaska. Volunteer groups, the NTC, the State of Alaska, and the KPB carry out most of the governmental functions in the area, like fire-fighting (volunteer), highway snow-removal (state), health services (NTC), and primary and secondary schooling (KPB). A Russian Orthodox church, the Holy Transfiguration of Our Lord Chapel, is located in the community.
Ninilchik is a popular tourist attraction. Other attractions in the area are salmon fishing, typically now either with commercial guides or private commercial family operations, either along the beach north of Ninilchik River or in Cook Inlet whose waters touch the beach next to the village. Halibut can also be caught in Cook Inlet close to Ninilchik. Pacific Razor Clams  are popular for digging on the beaches near Ninilchik, when the tides are low enough.
Ninilchik is also the host community for the annual Kenai Peninsula Fair.
