Jacob Niclas Ahlström was a Swedish Kapellmeister and composer.
Ahlström composed two operas based on libretti by Frans Hedberg, incidental music (for plays such as Agne, Positivhalaren, Ringaren i Notre Dame, and Hinko och Urdur), a vocal symphony, chamber music, and lieder. Together with Per Conrad Boman, he published Svenska folksånger, folkdanser och folklekar, the best-known collection of Swedish folk songs which appeared during the 19th century. In 1852, he also published the Musikalisk fickordbok (Musical Pocket Book), which enjoyed several reissues.
