Lechia Lwów (full name: Lwowski Klub Sportowy "Lechia" Lwów) was the first Polish professional football club, founded in summer 1903 in Lwów.
During the Second Republic of Poland the club was one of four teams from Lwów that played in the Polish Football First league (season 1931 – 12th). The club became two times champion of Lviv District League (liga okręgowa) where it spent 17 seasons. After invasion of Poland by the Soviet forces in 1939 the club was reorganized as FC Lokomotiv Lviv. The club's name comes from Lechia, a poetic name for Poland. The club's tradition as a Polish club was continued by people expelled from Lwów who moved to Gdańsk and created Lechia Gdansk after war in 1945.
