Elektrit Radiotechnical Society (Polish: Towarzystwo Radiotechniczne „ELEKTRIT”) was the largest privately owned company in Wilno, Second Republic of Poland (now Vilnius, Lithuania) (1925–39).^[1]

With over 1100 workers, the society produced approximately 50 thousand radio receivers annually.^[1] A large percentage of the production was exported abroad, mostly to Sweden, Germany, Czechoslovakia and Yugoslavia.^[1] The annual turnover exceeded US$1 million.^[1] Elektrit proved to be a very successful company and soon became a leading radio manufacturer in Poland.

Following the Soviet invasion of Poland in 1939, Wilno was occupied by the Soviet Union and the company was nationalized.^[1] In 1940 the factory was hastily dismantled and transported to Minsk, where the "Vyacheslav Molotov" Radio Factory was set up.^[1] After the war the plant was renamed Minsk Radio and Television Association "Horizont" (Horizon). It produced "Minsk" radio receivers, being copies of Polish pre-war models but with Soviet tube set.

The former Elektrit buildings in Vilnius were used for the Kailis forced labor camp during the German occupation^[2] and by a secret Soviet radio factory of the Ministry of Aviation Industry, known as PO Box 555.^[3]
