This is a list of wars that the Republic of Latvia has participated in.
According to the theory of state continuity of the Baltic states, the republic of Latvia existed as a de jure sovereign state from 17 June 1940 to 4 May 1990 and was represented by the Latvian Diplomatic Service, which controlled limited state functions during its occupation. Latvia did not engage in warfare during this period.
*e.g. result unknown or indecisive/inconclusive, result of internal conflict inside Latvia, status quo ante bellum, or a treaty or peace without a clear result.
