Beilstein (German pronunciation: [ˈbaɪlʃtaɪn] ⓘ) is a town in the district of Heilbronn in Baden-Württemberg in southern Germany.

The communal land of Beilstein includes big parts of the Löwenstein Mountains.

Neighbouring towns and municipalities of Beilstein are (clockwise from the south): Oberstenfeld, Großbottwar (both in the district of Ludwigsburg), Ilsfeld, Abstatt, Lauffen am Neckar (exclave Etzlenswenden), Löwenstein (all in the district of Heilbronn) and Spiegelberg (Rems-Murr-Kreis).

Beilstein has combined with Abstatt, Ilsfeld and Untergruppenbach to form a joint association of administrations called Schozach-Bottwartal.

The neighbouring hill Stocksberg is the highest one of the Löwenstein Mountains, however, it doesn't belong to the communal land of Beilstein.

The hamlets Billensbach, Gagernberg, Jettenbach, Kaisersbach, Klingen and Maad belong to Schmidhausen.

[3] Beilstein developed during the Middle Ages adjacent to Hohenbeilstein Castle, which was built around 1080.

After overlordship of the castle passed to the Margraves of Baden in 1234, the settlement was promoted to town status between 1250 and 1288 and is first mentioned as such in 1304.

Bavarian soldiers occupied trade routes to Heilbronn and Schwäbisch Hall, so there was no possibility to buy grain when there was a huge crop failure.

In 1628 there were further losses due to the invasion of Wallenstein's troops, demanding 65 bushels of grain in 1629.

Eberhard III fled to Straßburg, so victorious imperial troops looted and burned down many towns and villages.

Once the French were able to advance to Lauffen, where Württemberg's troops beat them and forced them back.

During the second invasion the French destroyed Marbach and advanced to Großbottwar, Oberstenfeld, Beilstein and Auenstein.

Beilstein was burned down almost completely: 105 houses, 30 barns, and the town hall were destroyed.

In March 1945 the front line came nearer, and army units entered the town, which became the target of a heavy air-raid in the afternoon of April 16, 1945.

After 1970 the population increased heavily as Beilstein became attractive to commuters driving to Heilbronn, Ludwigsburg and Stuttgart.

Due to a state program of redevelopment, decisive actions were taken in 1982 to change the town's image.

Until the 17th century the seals of Beilstein showed just one hatchet being the Fleckenzeichen simultaneously.

The district council of Beilstein confirmed the current form of arms on February 5, 1930.

In 1805 its use as a church ended, and thereafter it served as a military hospital, ammunition dump, and a gym.

Even other timber buildings show the reconstruction of the town, e. g. the neighbouring Alte Schmiede (old smithy).

In the Weinbergfest underneath Hohenbeilstein Castle taking place every last weekend in July there are shown Beilstein's sparklings and wines.

Beilstein is a station of the Bottwartalbahn running from Marbach am Neckar to Heilbronn.

For happenings in Beilstein, the newspaper Heilbronner Stimme is published daily.
