Dupnitsa, or Dupnica (Bulgarian: Дупница (previously Дубница), pronounced [ˈdupnit͡sɐ]), is a town in Western Bulgaria. It is at the foot of the highest mountains in the Balkan Peninsula – the Rila Mountains, and about 50 km (31 mi) south of the capital Sofia. Dupnitsa is the second largest town in Kyustendil Province.

The town has existed since ancient times. The German traveller Arnold von Harff visited Dupnitsa in 1499 and described it as a "beautiful town". The names Tobinitsa, Doupla and Dubnitsa are mentioned throughout history, the last one used until the Liberation of Bulgaria, when the official name was changed to Dupnitsa. In 1948 the town was renamed Stanke Dimitrov; for a short period in 1949 it was called Marek; the name was changed to Stanke Dimitrov in 1950. After the democratic changes, the old name Dupnitsa was restored.

On 15 October 1902, around 600 women and children fled to the vicinity of Dupnitsa from Macedonia from the attacking Turkish troops.

On a hill overlooking the town there is a giant cross, commemorating the Bulgarians who perished in the Balkan wars and World War I. On the same hill there lay the ruins of a medieval fortress.

During World War II over 4,000 Jews from parts of Greece and Yugoslavia annexed by Bulgaria were arrested on 4 March 1943 and deported, some to an internment camp in Dupnitsa. Many of them were from Komotini and Xanthi. After 11 to 12 days in the Dupnitsa camp, on 18 – 19 March they were transferred by train to Lom on the Danube for extermination at Treblinka. As part of the Bulgarian Commissariat for Jewish Affairs's policy of deporting Jews, Dupnitsa also was between June 1943 and September 1944 the site of a ghetto for 1,624 Jews expelled from Sofia, even though there was ultimately no exterminations of Jews resident within Bulgaria's pre-war borders.

Nowadays Dupnitsa is a fast-developing town combining new buildings with modern architecture with its historical monuments. Because of its beautiful location at the foot of the Rila mountain, the town is marvelous holiday destination. One of the main branches of industry is the pharmaceutical company Actavis (formerly HeFeKa, in Bulgarian ХФК), which gives employment to about 30 to 40 percent of the citizens. Small business is developing rapidly due to the town's economic growth.

Dupnitsa is famous for its cultural festivals. From 1 May to 2 June many festivals are held in the town due to the richness of the Bulgarian holiday calendar. The nightlife is very well developed. There are a lot of local pubs and clubs where young people meet and have fun. A few other popular places for socializing are the recently refurbished Town Park and the Town Garden (Градска градина, Gradska gradina).

In recent years the town has become notorious due to the activities of an organised crime group led by pair of Bulgarian gangsters, former policemen Angel Hristov and Plamen Galev, known as the "Galevi brothers". Using intimidation and extortion, and with the help of corrupt policemen, they controlled Dupnitsa to the extent that they have been described as "the owners of the first private town in Bulgaria". Hristov and Galev are fugitives after having been sentenced to five and four years respectively but are still believed to control the town.

Dupnitsa is referred to as "The Green and Shady Town", because of its location which makes it quite shady in summer and due to the abundance of trees in the town. Dupnitsa is called "The Little Italy of Bulgaria". This nickname comes from the fact that many inhabitants have gone over the years to work and live in Italy and every summer they return to their home town (see: Bulgarians in Italy). Another nickname of the town is "the town of pharmacy".
