Ernst Bröer (* April 11, 1809 in Ohlau, Lower Silesia; † during the night from the 25th to 26th of March 1886 in Tarnopol, Galicia) was a German organist and musician.
Bröer moved from his hometown to Breslau, Silesia, where he worked almost forty years as an organist and choir director at the ''St. Dorotheenkirche'' (Dorothea Church). From 1843 until 1884 Bröer was employed as a teacher for singing at the royal Catholic ''Matthiasgymnasium'' (Matthew Secondary School). During the period of the 1830's and 1840's, Ernst Bröer was considered to be the best violoncello virtuoso in the entire city. Furthermore, he was active as a church composer and wrote among other things eight masses. Bröer taught singing at the ''Breslaur Ursulinerkloster'' (Breslau Ursuline Convent) during the 1870's. In 1884 he gave up all of his offices and moved into the Jesuit monastery in Tarnopol where he passed away during the night from the 25th to 26th of March as a result of an ischemic stroke.
