Tannenfels Castle (German: Burg Tannenfels) is a ruined hill castle of the motte and bailey type which stands at a height of 460 m above sea level (NN) above the village of Dannenfels on the Donnersberg hill in the county of Donnersbergkreis in the German state of Rhineland-Palatinate.

Around 1368 Henry II of Sponheim-Bolanden moved his family seat to nearby Kirchheimbolanden.

On 20 December 1354, Archbishop Gerlach of Mainz bestowed a benefice for the aforementioned Chapel of St. Mary, which was endowed by Philip of Sponheim-Bolanden.

In a deed dated 4 January 1449 the vicar general of Mainz, Siegfried Piscator, entrusted pastoral care in this chapel to the nearby Abbey of St. James.

In a description of the Kirchheim estate in 1657 it is stated that a Protestant priest lived in Dannenfels, but he had to preach in the parsonage because there was no church in the village.
