The Oboe Concerto in D minor, S D935, is an early 18th-century concerto for oboe, strings and continuo attributed to the Venetian composer Alessandro Marcello. The earliest extant manuscript containing Johann Sebastian Bach's solo keyboard arrangement of the concerto, BWV 974, dates from around 1715. As a concerto for oboe, strings and continuo group, its oldest extant sources date from 1717: that year it was printed in Amsterdam, and a C minor variant of the concerto, S Z799, was written down. In the 19th century, Bach's keyboard version was published falsely attributing the concerto to Antonio Vivaldi. In 1923 the C minor version of the oboe concerto was published falsely attributing the concerto to Benedetto Marcello, Alessandro's brother. In the second half of the 20th century several publications indicated Alessandro again as the composer of the piece, as it had been in its early 18th-century print, and the oboe concerto was again published in its D minor version. In the 20th and 21st centuries the concerto developed into a well-established repertoire piece, as well as an oboe concerto as performed on keyboard.

The oboe ( OH-boh) is a type of double-reed woodwind instrument. Oboes are usually made of wood, but may also be made of synthetic materials, such as plastic, resin, or hybrid composites. The most common type of oboe, the soprano oboe pitched in C, measures roughly 65 cm (25+1⁄2 in) long and has metal keys, a conical bore and a flared bell. Sound is produced by blowing into the reed at a sufficient air pressure, causing it to vibrate with the air column. The distinctive tone is versatile and has been described as "bright". When the word oboe is used alone, it is generally taken to mean the soprano member rather than other instruments of the family, such as the bass oboe, the cor anglais (English horn), or oboe d'amore. Today, the oboe is commonly used as orchestral or solo instrument in symphony orchestras, concert bands and chamber ensembles. The oboe is especially used in classical music, film music, some genres of folk music, and is occasionally heard in jazz, rock, pop, and popular music. The oboe is widely recognized as the instrument that tunes the orchestra with its distinctive A. A musician who plays the oboe is called an oboist.
