Oka

Oka is a proper noun used across regions and languages, most commonly associated with watercourses and place names in Russia, as well as with historical events in North America. The most prominent feature bearing the name is the Oka River, a river in European Russia that flows toward the Volga.

In Russia, Oka is the name of multiple rural localities and administrative districts, reflecting common toponymic practice where geographic features lend their names to settlements. The term appears in various forms in regional names and institutions.

Outside Russia, Oka is associated with the Oka Crisis, a 1990 stand-off in Quebec between the Mohawk community at Kanesatake and authorities over a planned land development on disputed territory, which drew national attention to Indigenous land rights and policing.

As a personal name, Oka appears as a surname and given name in several cultures, including Japan, and may be found in other regions through diaspora communities.
