Ludmilla Elisabeth of Schwarzburg-Rudolstadt (also Ludomilla or Ludämilie; 7 April 1640 – 12 March 1672 in Rudolstadt) was a German noblewoman and a hymn poet.

Ludmilla Elizabeth was a daughter of Count Louis Günther I of Schwarzburg-Rudolstadt and his wife Countess Emilie of Oldenburg-Delmenhorst.

Her father died in 1646 and she was raised in a strictly Protestant fashion by her mother.

[citation needed] After her mother died in 1670, Ludmilla and her three sisters moved to their brother's residence in Rudolstadt.

[citation needed] Her hymns were published in Rudolstadt in 1687 under the title Die Stimme der Freundin, d. i. Geistliche Lieder, welche aus brünstiger und biß ans Ende beharrter Jesusliebe verfertigt und gebraucht Weiland die Hochgebohrne Gräfin und Fräulein Ludämilia Elisabeth, Gräfin und Fräulein zu Schwartzburg und Hohensteins Christseligen Andenckens ("The voice of a friend, i.e. spiritual songs in memory of the Honourable Ludämilia Elizabeth, Countess of Schwarzburg and Baroness of Hohenstein, who fervently and persistently loved Jesus, her Saviour").
