Skarżysko-Kamienna (pronounced [skarˈʐɨskɔ kaˈmʲɛnːa] ) is a city in northern Świętokrzyskie Voivodeship in south-central Poland by Kamienna river, to the north of Świętokrzyskie Mountains; one of the voivodship's major cities. Prior to 1928, it bore the name of Kamienna; in less formal contexts usually only the first part of the name (Skarżysko) is used. It belongs to historic Polish province of Lesser Poland.

Skarżysko-Kamienna is an important railroad junction, with two main lines (Kraków – Warsaw and Sandomierz – Koluszki) crossing there.

The present-day districts of Łyżwy and Nowy Młyn were the locations of Paleolithic industrial settlements, which are now archaeological sites, part of the Rydno Archaeological Reserve, consisting of several hundred former Paleolithic sites stretching from Skarżysko-Kamienna to Wąchock. The sites were discovered in 1923–1925.

In 1173, the knights' congress gathered in Milica village (now the town's district) led by Casimir II The Just. Within the Polish Kingdom, Skarżysko was a private village of Polish nobility, administratively located in the Radom County in the Sandomierz Voivodeship in the Lesser Poland Province. Around 1885 Kamienna became an important rail junction on the newly built Ivangorod-Dąbrowa Railway. The main line of the railway connecting Ivangorod (Dęblin) and Dąbrowa Górnicza ran through the town from north to south, and two branch lines to Ostrowiec Świętokrzyski and Koluszki radiated from the town east and west, respectively. This spurred the growth of Kamienna from a village into a sizeable town by 1920, when it had about 20 enterprises employing 1000 workers, as well as railway workshops employing an additional 1000 workers.

In 1923, the commune of Kamienna was granted the status of a town. In 1922 the government of Poland decided to build an ammunition factory in Kamienna, to be called Państwowa Wytwornia Uzbrojenia Fabryka Amunicji (P.W.U. Fabryka Amunicji, "National Armament Factory - Ammunition Plant") It began production in 1924 supplying munitions to the Polish Army. It employed 2760 workers in 1932, over 3000 in 1936, and over 4500 in 1939, becoming the principal employer in the town and driving its growth. The company still functions today under the name Zakłady Metalowe MESKO S.A.).

In 1928, town's name was changed to Skarżysko-Kamienna. In 1937 the town had 19,700 inhabitants, among them 2,800 Jews (about 14% of the total).

Following the September 1939 invasion of Poland by Germany, which started World War II, Skarżysko-Kamienna was under German occupation until liberated by the Soviet army in January 1945. The Germans controlled the ammunition factory to support their own war effort, and from 1940 it was controlled by the company Hugo Schneider Aktiengesellschaft (HASAG), which ran it as a subcontractor for the Wehrmacht. In 1940, the Germans carried out mass executions of Poles (360 people executed in February and 760 in June). The Polish underground resistance organization Orzeł Biały ("White Eagle") was organized in the town. Among its members were local monks, and a weapons depot used by Polish partisans was located in the local monastery. Several monks were arrested and murdered by the Germans in the massacre committed in February 1940, while one managed to escape arrest.

The ghetto for the town's Jewish population was established by the Germans in April or May 1941. Between August 1942 and summer of 1943 Jews from the Radom district were brought to three camps near the munitions factory to work the factory. According to German records, of the total 17,210 brought in with 58 transports, 6,408 managed to survive long enough to be evacuated to other camps when the Germans closed the factory in 1944. The ghetto was liquidated in October 1942, with some inhabitants judged fit for work moved to the factory labour camps (about 500 out of 3000), and the rest were transported to Treblinka. In the major monograph on the subject estimated that despite the incompleteness of German records which likely underestimate the number of inmates, about 25,000 Jewish inmates were brought to the camp and 7,000 were evacuated from it; about 18,000 died there. The secret Polish Council to Aid Jews "Żegota", established by the Polish resistance movement, operated in the town. There are several known cases of Poles, who were either executed on sight or imprisoned in the local prison and deported to concentration camps for rescuing and aiding Jews.

In April 1942, the Germans founded the Stalag 380 prisoner-of-war camp, which several months later was relocated to Oppdal and Dombås in German-occupied Norway.

At least nine Boy Scouts and two Girl Scouts from the town were murdered by the Germans during the occupation (see Nazi crimes against the Polish nation). The monk who managed to avoid capture by the Germans in 1940, died in the Soviet bombing of the town in 1945.

On January 18, 1945 the town was liberated and restored to Poland, although with a Soviet-installed communist regime, which remained in power until the Fall of Communism in the 1980s. About a dozen Jewish survivors returned to Skarżysko-Kamienna in the winter of 1945-1946 to retrieve Jewish property. Soon afterwards, in February 1946, five of them were murdered for profit by a small group of local criminals. The murderers, among them the head of the Soviet-installed town police and another communist policeman, were put on trial in Łodź. Three of them received the death penalty. The remaining Jews left Poland, except for Dr. Zundel Kahanel and his wife Bima who spent the rest of their lives in the city.

Meanwhile, in 1948 the leading HASAG managers were tried in Leipzig in the Soviet occupation zone in Germany. Of the 25 tried, 4 were sentenced to death, 2 to life in prison, and 18 to terms between one and five years.

In 1969, The White Eagle Museum was established. In 1984, town limits were expanded by including the neighboring settlements of Łyżwy and Nowy Młyn as new districts. In 1999, Skarżysko County was established as a result of the Local Government Reorganization Act (1998).
