Rückweiler is an Ortsgemeinde – a municipality belonging to a Verbandsgemeinde, a kind of collective municipality – in the Birkenfeld district in Rhineland-Palatinate, Germany. It belongs to the Verbandsgemeinde of Baumholder, whose seat is in the like-named town.

The municipality lies in the Hunsrück, at Rhineland-Palatinate's boundary with the Saarland. The municipal area measures roughly 274 ha, and the elevation is 524 m above sea level.

Rückweiler borders in the north on the municipality of Berglangenbach, in the east on the municipality of Rohrbach, in the southeast on the municipality of Freisen, in the southwest on the municipality of Hahnweiler and in the northwest on the municipality of Leitzweiler. Rückweiler also meets the municipality of Gimbweiler to the west at a single point, which is also shared with two other municipalities. All municipalities named here are in the Birkenfeld district but for Freisen, which is in the Sankt Wendel district in the Saarland.

Bearing witness to early habitation in the Rückweiler area are grave goods from the Iron Age going back as far as the 6th century BC. The people of the Hunsrück-Eifel culture were Celtic, raised livestock, and were also already raising crops. They burnt their dead and buried them with their belongings. Their “princes”, however, were buried in great mounds under hefty stones. An extensive burying ground was discovered near Rückweiler on the western slope of the Rückeberg. This discovery and other burying grounds in Freisen and near Hoppstädten-Weiersbach show that the region was already attracting settlers then.

The Rückweiler burying ground comprised 12 graves sunk into the rock within an area of 3 000 m² at a sport field, which now no longer exists. Brought to light from these graves were handmade and thrown pots of various shapes. The way that the graves were laid out as a group suggested that the burying ground was a family plot, or perhaps one used by an estate. The graves were either elliptical or rectangular and more than a metre long. They lay as far down as 90 cm below the ground and were filled with dark earth coloured by charcoal remnants. The number of pots found in each grave varied from one to ten. For the voyage to the hereafter, some pots contained food, jewellery, items of clothing and other belongings. One peculiarity was the graves’ superstructures, which had, of course, long since vanished. However, the upright posts of these structures had left dark soil where they had once been sunk into the earth. The superstructure remnants at two of the graves suggested that the superstructures might have been replicas of the dead's houses, further suggesting a Mediterranean influence from La Tène times. The superstructures served as remembrance to the dead and also were important in the care of the departed souls, for the builders believed that without such care, the dead were left to wander about without peace, bringing the living bad luck and harm. To ward off any such outcome, the dead were given food, drink and sacrifices.

According to old documents, the Rückweiler area belonged in the 12th century to the Bishop of Verdun. Even the Counts of Veldenz, who as fiefholders ruled the land, named the Bishop as the actual landowner. Given this, it can easily be concluded that the whole area once belonged to a greater landhold, Tholey, which Deacon Adelgisel, known as Grimo, a great Merovingian landholder, donated to the Church of Verdun on 30 December 634.

On 5 March 1332, Rückweiler had its first documentary mention under the name Rickwilre. In the villages of Rohrbach and Rückweiler, which belonged to the Pflege (literally “care”, but actually a local geopolitical unit) of Rohrbach, the land was held, as it was in the neighbouring court district of Baumholder at that time, by enfeoffed lords. On the date in question, Dietrich Gauwer von Lichtenberg allocated 299 Mark Pfennige from his holdings in Rohrbach and Rückweiler for his wife as a dower. In 1386, Johann von Lewenstein paid Count of Veldenz Heinrich 100 Gulden (roughly equivalent to €4000 or €5000 in modern funds) for his villages, courts, paupers, water and meadowland at “Roirbach, Zingswilre und Rickwilre” along with three bondsmen outside these villages. In 1428, the Count of Veldenz awarded the court fief to the House of Winterbecher. Three years later, half of each of the two villages of Rohrbach and Rückweiler, along with their people, interest payments and earnings, were under Count of Sponheim Wolf's ownership. He in turn sold the rights along with other goods and sources of income for 487.5 Gulden to Count of Veldenz Friedrich. The other halves of the fiefs of Rohrbach and Rückweiler were held by the family Gauwer von Lichtenberg, and thereafter by Hildebrand von Boxberg. Owing to disputes between Count of Veldenz Stephan and Lord of Oberstein Wyrich von Dhaun, a judicial decision on 26 January 1440 stipulated that the Boxberg fief of Rohrbach, Rückweiler and Würtzweiler was to be awarded in whole to the House of Veldenz. Four years later, when the House of Veldenz died out in its male line, Rückweiler passed to Stephen, Count Palatine of Simmern-Zweibrücken.

In the Thirty Years' War, the region around Rückweiler suffered heavily. Subsequently, as a result of brutal Rhine campaigns by Louis XIV's troops in the Franco-Dutch War, in 1675 Rückweiler had only one family left.

In French Revolution’s wake, Rückweiler, having formerly belonged to the Amt of Berschweiler, and for a short while to the Amt of Nohfelden, was assigned under French rule, beginning in 1793, to the Mairie (“Mayoralty”) of Berschweiler in the canton of Baumholder As such it was incorporated into the First French Empire under Napoleon.

At the Congress of Vienna, Rückweiler was granted to Duke Ernest III of Saxe-Coburg-Saalfeld as part of a large estate of some 8.25 square miles, at first called the Herrschaft Baumholder; by a ducal decree of 6 March 1819, the area between Baumholder and Kusel was renamed the Principality of Lichtenberg. In 1834, however, due to political unrest and its great distance from the rest of his Duchy, Duke Ernest sold the Principality to Prussia for an annuity of 80,000 talers.

Thereafter the village formed a part of the Prussian Rhine Province and from 1871 a part of the German Empire. Following the abdication of the last emperor in 1918, the province was included in the newly established Free State of Prussia in the Weimar Republic; in 1920 it was made part of the League of Nations protectorate known as the Saargebiet, until a plebiscite returned the territory to the German Reich in 1935. From the fall of the Reich in 1945, the area was part of the French occupied zone.

The council is made up of 8 council members, who were elected by majority vote at the municipal election held on 7 June 2009, and the honorary mayor as chairman.

Rückweiler's mayor is Lutz Altekrüger.

The German blazon reads: In geteiltem Schild oben in Silber ein rotbewehrter und gezungter wachsender blauer Löwe, unten in Grün ein goldener, mit rotem Band umwundener Erntekranz, belegt mit einem goldenen Kreuz.

The municipality's arms might in English heraldic language be described thus: Per fess, argent issuant from the line of partition a demilion azure armed and langued gules, and vert a wreath Or and gules surmounting the three short arms and surmounted by the lower arm of a cross Latin issuant from base of the fifth.

The charge in the upper field, the lion, is a reference to the village's former allegiance to the County of Veldenz. The composition of charges in the lower field is known as a harvest cross (Erntekreuz in German) and refers to the municipality's yearly harvest festival in which thanks are given for the harvest.

The arms have been borne since 25 November 1965.
