Symphony No. 3 (1938) is a symphony in four movements composed by American composer Howard Hanson (1896–1981). The first three movements were finished in 1936, a revision in 1938 added the finale movement to the symphony. A typical performance time is approximately 36 minutes. The work, commissioned by the CBS Symphony Orchestra, was written in commemoration of the 300th anniversary of the first Swedish settlement in Delaware in 1638.
