Jilemnice consists of three municipal parts (in brackets population according to the 2021 census): • Jilemnice (4,526) • Hrabačov (704) • Javorek (17)

The name was derived from the Czech word jilm ('elm') and from the adjective jilemná (meaning 'flowing between elms'), related to some water course.

Jilemnice is located about 12 km east of Semily and 34 km southeast of Liberec. It lies in a hilly landscape of the Giant Mountains Foothills. The highest points are the slopes of the Chmelnice hill at 592 m above sea level, and the peak of Bubeníkovy vrchy at 588 m. The Jizerka River flows through the northern part of the municipal territory. The Jilemka Stream flows through the town into the Jizerka.

Jilemnice was founded probably in the 1320s as an economic centre of an extensive Štěpanice estate owned by the Waldstein family. The regular ground plan of the historic centre indicates that the town was probably founded on a green field. Because of its secluded location, the town developed in a slower pace than other towns in fertile inland. However, Jilemnice's isolation protected the town against serious war damage for years. The town development was even more restricted from 1492, when the Waldstein family divided the estate into two parts. In the 15th and 16th centuries, the main economic activities were ore mining and linen production. During the Thirty Years' War, Jilemnice was burned down by the Swedish army and after the war, the town failed to follow up on the previous sources of livelihood. In 1701, both parts of the estate were acquired and merged by the Harrach family. Since then, Jilemnice began to prosper again. Harrachs' progressive economic policy led to raising of local linen industry to the world level. During the first half of the 19th century, the linen industry gradually declined. In 1873, the Textile Industrial School was founded. Jilemnice continued to develop in the interwar period and became a tourist resort, but the war had a negative impact on the economy and tourism. After the war, the town's economy shifted to the engineering and food industries.

The church was built in the Baroque style in 1729–1735.
