A "kotiryssä" (literally "Home Russian") was a Soviet or Russian contact person of a politician, bureaucrat, businessman or other important person in Finland.
 The term "kotiryssä" referred especially to Soviet spies stationed in Helsinki in the 1960s and 1970s who were designated by the Soviet government to gather information from specific persons in Finnish politics and government.
 As such information gathering techniques have arguably always been prevalent among spies, some Finns have argued that the "kotiryssä" system was a normal way to conduct diplomatic relations between two countries.
 The dozens of KGB officers working out of the Tehtaankatu embassy of the Soviet Union is now well documented.
 The public did not know about the system until the book "Tamminiemen pesänjakajat" was published in 1981.
 The "kotiryssä" system was closely related to Finlandization.
