Heckelphone (German: Heckelphon) is a double reed instrument of the oboe family. It is pitched an octave below the oboe and furnished with an additional semitone taking its range down to A.^[1], with a wider bore and hence a heavier and more penetrating tone.

The heckelphone was invented by Wilhelm Heckel and his sons, and introduced in 1904. It was intended to provide a broad oboe-like sound in the middle register of the swollen orchestrations of the turn of the twentieth century. In the orchestral repertoire it is generally used as the bass of an oboe section incorporating the oboe and the cor anglais (English horn), filling the gap between the en:oboes and en:bassoons.
