(The North Star) is an opéra comique in three acts by Giacomo Meyerbeer. The French-language libretto was by Eugène Scribe. The work had its first performance at the Opéra-Comique, Paris, on 16 February 1854. Much of the material, including some plot similarities (with the flautist Frederick the Great substituted by the flautist Peter the Great), derived from Meyerbeer's earlier 1844 Singspiel Ein Feldlager in Schlesien. However, there also are some significant differences, perhaps the most important of which is that it was permissible to actually have Peter the Great take part in the action, which was not the case for Frederick, who had to play his flute off-stage, since members of the Prussian royal family were not permitted to be impersonated on the stage in Berlin where that work had its premiere. Peter does more than just take part in the action, since he ends up being the romantic lead. A notable feature of the opera is the triple march in the finale to the second act. A rebellion against the Tsar is deflected as the "sacred march" is heard. The troops are then joined by a regiment of grenadiers from Tobolsk, to the music of a different march, followed by a regiment of Tatar cavalry to the music of a third march.

Ships' carpenters rest from their work and enjoy a meal break as Danilowitch, a pastry-chef from Russia, hawks his pies. Among the carpenters are Peter the Great of Russia, disguised as the lowly Peters Michaeloff. The absence of the lovely Catherine, who usually serves the workers, is noted, and the carpenters tease Peters for being in love with her, which annoys him. The carpenters propose a toast to Charles XII of Sweden, Russia's enemy, which angers Danilowitch and Peters, both of whom are Russian. The bell rings for the carpenters to return to work, and a potentially ugly scene is averted. Left alone, Peters tells Danilowitch that he is indeed in love with the beautiful Catherine and has even learned, like her brother Georges, to play her favourite tune on the flute
