Walcker Orgelbau (also known as E. F. Walcker & Cie.) of Ludwigsburg, Baden-Württemberg, Germany, is a builder of pipe organs. It was founded in Cannstatt, a suburb of Stuttgart in 1780 by {{ill|Johann Eberhard Walcker|de}}. His son Eberhard Friedrich Walcker moved the business to Ludwigsburg in 1820.[http://www.walckerorgel.de/gewalcker.de/english/english.htm History of the Walcker family]

Walcker first became famous for the organ it built in the Paulskirche, Frankfurt, in 1833, which had 74 stops. Other important commissions followed rapidly, and Walcker became a pioneer of the "symphonic organ" style in Germany.

Known for distinguished installations and low output, the company built the organs for the Boston Music Hall in Boston, Massachusetts, Zagreb Cathedral in Zagreb, Croatia, University of Latvia,[http://foto.lu.lv/HI-RES/arhiivs/2013/i_sep/27/IMG_7665.JPG University of Latvia Main hall organ, built in 1937] Riga Cathedral and Church of Luther in Riga, Latvia.{{Cite web |last=Walcker-Mayer |first=Gerhard |date=March 2003 |title=The Organ in Riga Cathedral as viewed by the Walcker firm |url=http://www.walckerorgel.de/gewalcker.de/Riga_eng.htm |url-status=dead |archive-url=https://web.archive.org/web/20031228235957/http://www.walckerorgel.de/gewalcker.de/Riga_eng.htm |archive-date=December 28, 2003}}{{cite web | last=Magle | first=Frederik | title=The Walcker Organ in Riga Cathedral | date=7 July 2005 | url=http://www.magle.dk/music-forums/801-walcker-organ-riga-cathedral.html | access-date=11 July 2007}}{{Cite web |title=Zudusī Latvija - Rīgas Lutera baznīca Torņkalnā |trans-title=Riga Lutheran Church in Torņkalns |url=https://www.zudusilatvija.lv/objects/object/27022/ |access-date=2023-02-08 |website=www.zudusilatvija.lv}} The Boston instrument is now at the Methuen Memorial Music Hall in Methuen, MA.
