Shivachevo (Bulgarian: Шивачево) is a small town in the Sliven Province located on the southern slopes of the Balkan Mountains in central eastern Bulgaria.

The area around the present town of Shivachevo has been inhabited since ancient times. Numerous archeological artifacts have been found in the area. Thracian earthenware used during funeral ceremonies and containing burnt bones and wheat were found in the yard of the present-day school. Other discoveries include a Thracian bronze helmet, Roman coins, and Byzantine coins with the faces of the emperors Justinian I and Nikiforos Foka.

From the distant past the inhabitants of Shivachevo were famous for their patriotic spirit. They aided the volunteer detachments (called "haidushki chet") who fought against the Turkish rule during the 19th century. After the Crimean War (1853–1856) and the new Turkish laws that followed it, a committee was established in Shivachevo in 1857 for building a church which was finished in 1859 and was given the name of St. Dimitar. The town celebration is held on October 26 every year on St. Dimitar's Day.
