S 10 (also Abydos-south S10) is the modern name given to a monumental ancient Egyptian tomb complex at Abydos in Egypt. The tomb is most likely royal and dates to the mid-13th Dynasty. Finds from nearby tombs indicate that S10 suffered extensive state-sanctioned stone and grave robbing during the Second Intermediate Period, only a few decades after its construction, as well as during the later Roman and Coptic periods. These finds also show that S10 was used for an actual burial and belonged to a king "Sobekhotep", now believed to be pharaoh Sobekhotep IV (fl. c. 1725 BC). According to the Egyptologist Josef W. Wegner who excavated S10, the tomb might originally have been capped by a pyramid, although Aidan Dodson states that it is still unclear whether S10 was a pyramid or a mastaba.
