Football Club Rozova Dolina Kazanlak (Bulgarian: Футболен клуб Розова долина Казанлък) or simply known as Rozova Dolina (Bulgarian: Розова Долина) is a Bulgarian association football club based in the town of Kazanlak, Stara Zagora Province, which currently competes in the Bulgarian Third League, the third division of Bulgarian football. Their home ground since 1968 has been the Sevtopolis Stadium. The club's name is translated as Rose Valley and is named after the homonymous Rose Valley region of central Bulgaria, which also encompasses the town of Kazanlak.
The club was formed in 1948 as DNA Kazanlak, a football club characterized by its trademark red and white jerseys. In 1982-83, the team played at the top of the Bulgarian football league system, the A Group, but was subsequently relegated after only one season in the top flight, finishing in 15th place.
On January 15, 2016, following the team's return from the winter break, the club announced that they have reached an agreement with the local Bulgarian businessman Georgi Mermekliev, who would take over at the helm of the club. He subsequently announced his intentions to bring Rozova Dolina's previous glory over the years and that the team will be battling for promotion for the A Group in the very next seasons. He also stated that the club stadium would be renovated and upgraded to 12,000 seats and a new academy would be established. Subsequently, Rozova Dolona announced a sponsorship with a new kit manufacturer, Legea for the upcoming season. Following a great number of investments, on September 14, 2016, Rozova Dolina qualified for the Bulgarian Cup competition after 15 years absence from professional football.
