The Symphony No. 1 in D major, Op. 4 (JSV 38), is a four-movement orchestral work written from 1866 to 1867 by the Norwegian composer Johan Svendsen while he was a music student at the Leipzig Conservatory. The first movement premiered in Leipzig on 9 May 1866 at the Altes Gewandhaus, with Svendsen conducting; a year later in the same location, he conducted Movements II–IV for the first time. These earlier partial performances notwithstanding, the symphony—in its entirety—received its premiere in Kristiania, Norway, on 12 October 1967, again under the composer's baton.
