Ein Feldlager in Schlesien (A Camp in Silesia) is a Singspiel in three acts by Giacomo Meyerbeer with a German-language libretto by Ludwig Rellstab after Eugène Scribe's Le camp de Silésie. It was first performed at the Hofoper, Berlin, on 7 December 1844; a version with a revised libretto by Charlotte Birch-Pfeiffer, titled Vielka, opened in Vienna on 18 February 1847. Much material from the opera was later reused for Meyerbeer's opéra comique L'étoile du nord (1854).
