The Symphony No. 4 in A major, Op. 90, commonly known as the Italian, is an orchestral symphony written by German composer Felix Mendelssohn (1809–1847).
The work has its origins, like the composer’s Scottish Symphony and the orchestral overture The Hebrides (Fingal’s Cave), in the tour of Europe which occupied Mendelssohn from 1829 to 1831. Its inspiration is the colour and atmosphere of Italy, where Mendelssohn made sketches but left the work incomplete.
