The Mausoleum at Halicarnassus or Tomb of Mausolus was a tomb built between 353 and 350 BC at Halicarnassus (present Bodrum, Turkey) for Mausolus, a satrap in the Persian Empire, and Artemisia II of Caria, who was both his wife and his sister. The structure was designed by the Greek architects Satyros and Pythius of Priene.

The Mausoleum stood approximately 45 m (148 ft) in height, and each of the four sides was adorned with sculptural reliefs created by each one of four Greek sculptors — Leochares, Bryaxis, Scopas of Paros and Timotheus. The finished structure of the mausoleum was considered to be such an aesthetic triumph that Antipater of Sidon identified it as one of his Seven Wonders of the Ancient World.

The word mausoleum has now come to be used generically for an above-ground tomb.
