Sömmerda is a town near Erfurt in Thuringia, Germany, on the Unstrut river. It is the capital of the district of Sömmerda.

Archeological digs in the area that is now Sömmerda, formerly Leubingen, have uncovered prominently buried human remains dating to around 2000 BCE. One such burial of an individual, dubbed the "king of Leubingen" is the Leubingen tumulus. Sömmerda was first mentioned in official documents in 876 CE. It probably became a town in about 1350 but there are no existing records of the event. One town gate, dating from 1395, and six towers from the old town walls are still standing. During the Thirty Years' War (1618–1648) Sömmerda was at the heart of military activity, and soldiers from both sides ransacked the town, halving the population. In 1840, Johann Nikolaus von Dreyse invented the needle gun and a firearms factory was founded in the town. In 1919 the Rheinmetall company took over the factory, later called Rheinmetall Borsig, at first to produce automotive parts. Initially it concentrated with only little success on carburettors, then in 1925 an ambitious new manager, the engineer Fritz Faudi, took over and a new type of cardan joint was developed, which became extremely popular. The Rheinmetall Faudi system was a well known name, and the Sömmerda works were the largest producer in Germany. In April 1921 the factory returned to arms production, going against the post war regulations which banned it from producing fuses. From October 1922 the factory produced the total quantity of fuses allowed in Germany by the Allies and also began producing the new MG30 machine gun under the direction of Louis Schmeisser. In September 1944 Rheinmetall Borsig became an external camp for Buchenwald concentration camp. As many as 1,294 female prisoners were made to do forced labour there, most of them aged between 16 and 60, many Jews from Hungary. As well as continuing to produce cardan shafts, the women also helped make parts for armoured vehicles used in the war, as well as manufacturing arms; two new workshops were built for this in 1944 and 1945. The SS evacuated the camp in early April 1945, sending its prisoners and SS overseers on a death march, which ended near Pilsen, Czechoslovakia. Today a special cemetery in Sömmerda contains graves and a memorial to the camp inmates, forced labourers and war prisoners. On April 11, 1945, Americans arriving in Sömmerda found the Rheinmetall plant still untouched by bombs, but abandoned by its managers. Days later Thuringia was occupied by the Russians, who recommenced production by the next month, employing between 1,000 and 1,500 workers. Production went back to automotive parts until the 1950s when office machinery began to be produced. Later Rheinmetall Borsig became today's Rheinmetall DeTec AG. Following the Second World War, the Sömmerda factory then found itself in the newly formed East Germany, with development and production now continuing as a state run enterprise, but using the pre war Rheinmetall name and logo. In 1957, a group of young electronics engineers under the collective direction of Heinz Skolaude brought Volkseigener Betrieb Büromaschinenwerk Sömmerda into being and into the age of electronics. In 1960 the name was changed to "Supermetall" and then in 1962 to the "Soemtron" name, when they exhibited at the Leipzig trade Fair of that year an electronic Fakturierautomaten (Automatic Invoicing machine) the model EFA 380. 1963 saw the next model the EFA 381 with magnetic core memory. In July 2018 the former municipality of Schillingstedt was merged into Sömmerda.

Sömmerda station lies on the Sangerhausen–Erfurt railway.
