The Symphony No. 26 in D minor, Hoboken 1/26, is one of the early Sturm und Drang Symphonies written by Joseph Haydn. It is popularly known as the Lamentatione. It was written under the auspices of Prince Nikolaus Esterházy, and is from the late 1760s, when Haydn began to experiment with minor key symphonic writing. It is also one of his first minor key symphonies.[citation needed]
