The Miraculous Mandarin (A csodálatos mandarin / Der wunderbare Mandarin) Op. 19, Sz. 73 (BB 82), is a one act pantomime ballet composed by Béla Bartók between 1918 and 1924, and based on the 1916 story by Melchior Lengyel. Premiered on 27 November 1926 conducted by Eugen Szenkar at the Cologne Opera, Germany, it caused a scandal and was subsequently banned on moral grounds. Although more successful at its Prague premiere, it was generally performed during the rest of Bartók's life in the form of a concert suite, which preserves about two-thirds of the original pantomime's music.

The scoring is generally heavy, and Bartók employs many colorful techniques here, including chromatic scales, trills and tremolos in the woodwinds; glissandi in the horns, trombones and tuba; cluster chords and tremolos on the piano; scales and arpeggios on the piano, harp and celeste; and scales, double stops, trills, tremolos, and glissandi in the strings. Other special effects include fluttertonguing in the flutes; muting the brasses and strings, a cymbal roll a deux (a cymbal crash followed by scraping the plates together); playing the bass drum with the wooden part of a timpani mallet; a roll on the gong; rolled timpani glissandi; string harmonics; col legno and sul ponticello playing in the strings; scordatura in the cellos; and, at one point, quarter-tones in the violins.
