Levski (Bulgarian: Левски [ˈlɛfski]) is a town in central northern Bulgaria, an administrative center of the homonymous Levski Municipality in the very southeast of Pleven Province.

Levski Municipality is located on a territory of 414 km2 in the Danubian plain, Tuchenishko-Dolnoosomski region. The predominant relief in the municipality is the plain relief - the town of Levski is located at about 70 m above sea level. The distance to the regional town of Pleven is 50 km. The climate is temperate continental.

The old name of Levski (until 1897) is Karaagach (from Turkish - Black Elm). Today's Levski station before the Liberation from Ottoman rule was inhabited mainly by Turks. Some called it Turkish Karaach, unlike the village of Bulgarian Karaach, today's Totleben.

In 1880 there were 1,082 inhabitants in Turkish Karaach. Six years after the Liberation, in 1884 a primary school was opened, and in 1887 a Bulgarian church was built.

In 1881, the government of Dragan Tsankov proposed in the National Assembly to study the construction of the railway line Sofia - Danube. With a law of 15 February 1883, construction began. At that time the railway junction Levski station was also built.

The line was officially opened by Knyaz Ferdinand on 8 November 1899 with the starting station Sofia - Roman - Pleven - Gorna Oryahovitsa - Shumen - Varna.

The village of Karaach at that time was inconspicuous, covered in mud, the houses small and unstable. In no way could it be compared with the settlements close to it, such as Letnitsa, Alexandrovo and others.

In 1945, a year after the September 9 coup d'état, the village of Levski became the first village in Bulgaria to be declared a city by the communist authorities. OTKZS "Komuna" was founded in the city.
