'''Sliven''' ({{langx|bg|Сливен}} {{IPA|bg|ˈslivɛn|}}) is [[List of cities and towns in Bulgaria|the eighth-largest city]] in [[Bulgaria]] and the administrative and industrial centre of [[Sliven Province]] and municipality in [[Northern Thrace]]. It is situated in the [[Sliven Valley]] at the foothills of the [[Balkan Mountains]].

Sliven is famous for its heroic [[Hajduk|Haiduts]] who fought against the [[Ottoman Turks]] in the 19th century and is known as the "City of the 100 [[voyvoda|Voyvodi]]", a Voyvoda being a leader of Haiduts.

The famous rocky [[massif]] Sinite Kamani (Сините камъни, "The Blue Rocks") and the associated [[Sinite Kamani Nature Park]], the fresh air and the mineral springs at [[Slivenski Mineralni Bani]] offer diverse opportunities for leisure and tourism. Investors are exploring the opportunity to use the local wind (Bora) for the production of electricity.

Another point of interest and a major symbol of the city as featured on the coat of arms, is the more than thousand-year-old Stariyat Briast (Старият Бряст, "The Old Elm"), a huge [[Smooth-leaved Elm]] in the center of the city. During Ottoman rule, Turkish officials used to hang Bulgarian revolutionaries on it. Today the city is helping the tree to live on by frequent evaluations and reinforcing its base. It was elected Bulgarian tree of the year in 2013. On 19 March 2014 the results of an online poll were revealed at a ceremony in the European Parliament. The Old Elm was voted [[European Tree of the Year]] 2014. The city also served as an important strategic centre for the [[Bulgarian Army]], with the headquarters of the Bulgarian Third Army located in the centre of the city, being situated relatively near to the sensitive Turkish border.

[[Sliven Peak]] on [[Livingston Island]] in the [[South Shetland Islands]], [[Antarctica]] is named after Sliven.
