Mt. Lebanon (locally /ˈlɛb.ə.nən/) is a township with home rule status in Allegheny County, Pennsylvania, United States. The population was 34,075 at the 2020 census. It is a first ring suburb of Pittsburgh located 4–6 miles (6–10 km) south of the city's downtown.

Established in 1912 as a farming community, Mt. Lebanon became a streetcar suburb with the arrival of transit lines and a real estate subdivision in 1901, offering easy access to Downtown Pittsburgh. The 1924 opening of the Liberty Tunnel further improved automobile access. In 1975, it adopted one of Pennsylvania's first home rule charters.
