Wilno-Troki County was a county with capital in Vilnius located in Wilno Land, and later, Wilno Voivodeship, in Poland. It originated from informal unification of administration, between the counties of Wilno and Troki, that existed from 1921 to 1922 within the Republic of Central Lithuania, and from 1922 to 1923 or 1924 in Poland. Between 1923 and 1924, two counties were officially joined to form one county, that until 1926 was located in Wilno Land, and from 1926 to 1939, in Wilno Voivodeship.
