The County of Sponheim (German: Grafschaft Sponheim, former spelling: Spanheim, Spanheym) was an independent territory in the Holy Roman Empire which lasted from the 11th century until the early 19th century. The name comes from the municipality of Sponheim, where the counts had their original residence.

The territory was located roughly between the rivers Rhine, Moselle and Nahe, in the present state of Rhineland-Palatinate, around the Hunsrück region. It bordered the Electorate of Trier to the north and west, the Raugraviate, the Electorate of Mainz and the Electorate of the Palatinate to the east and the County of Veldenz to the south and west, among other states.

The family of Sponheim, or Spanheim (German: Spanheimer), is documented since the 11th century. There are two main branches which are certainly related, but whose exact relationship is still debated. The branch of the Dukes of Carinthia descends from Siegfried I, Count of Sponheim. The Rhenish branch which retained the County of Sponheim descends from Stephan I, Count of Sponheim.

The county originated from various inheritances which were united in the family's hands, including possessions from the Counties of and Stromberg and jurisdiction of the Gaugrafen of Trechirgau (Berthold-Bezelin dynasty). The Sponheim comital office is supposedly derived from the comital office of Trechirgau. The family of the Counts of Sponheim founded the monastery of Sponheim in the 12th century, where in the 11th century a church had already been built. An abbot from Sponheim, Johannes Trithemius, chronicled the counts of Sponheim and accumulated a large collection of documents on the history of the area.
