Engelbert III of the Marck (German: Engelbert III von der Mark) (1304 - 1368) was the Archbishop of Cologne from 1364 until 1368 and the Bishop of Liège (as Engelbert) from 1345 until 1364.

Engelbert was the second son of Count Engelbert II of the Marck. Through the influence of his uncle Adolph II of the Marck, the Bishop of Liège he became in 1332 the Provost of Liège. Later he was also mentioned as being a Provost in Cologne.

After the death of his uncle he was appointed by Pope Clement VI the Bishop of Liège. In 1362 he applied to become the Archbishop of Cologne, but his nephew Adolph gained it in 1363. Nevertheless after Adolph abdicated in the following year he was appointed the Archbishop in 1364 by Pope Urban V and resigned the Bishopric of Liège. Engelbert was beset by health problems soon after taking office. In 1366 he accepted coadjutors to assist in the running of the archdiocese, and the Archbishop of Trier Cuno II of Falkenstein was selected. Engelbert died on 25 August 1368 and was buried in Cologne Cathedral.
