Usermaatre Heqamaatre Setepenamun Ramesses IV (also written Ramses or Rameses) was the third pharaoh of the Twentieth Dynasty of the New Kingdom of Ancient Egypt.

[4][5] His promotion to crown prince: is suggested by his appearance (suitably entitled) in a scene of the festival of Min at the Ramesses III temple at Karnak, which may have been completed by Year 22 [of his father's reign].

[7] As heir-apparent he took on increasing responsibilities; for instance, in Year 27 of his father's reign, he is depicted appointing a certain Amenemope to the important position of Third Prophet of Amun in the latter's TT 148 tomb.

It is now believed that Ramesses IV's mother was most likely Queen Tyti from recently discovered notes published in the 2010 issue of the Journal of Egyptian Archaeology.

At the start of his reign, the pharaoh initiated a substantial building program on the scale of Ramesses II by doubling the size of the work gangs at Deir el-Medina to a total of 120 men and dispatching numerous expeditions to the stone quarries of Wadi Hammamat and the turquoise mines of the Sinai.

His Majesty sent his favoured and beloved one, the confident of his lord, the Overseer of the Treasury of Silver and Gold, Chief of the Secrets of the august Palace, Sobekhotep, justified, to bring for him all that his heart desired of turquoise (on) his fourth expedition.

Panufer states that this expedition's mission was both to procure turquoise and to establish a cult chapel of king Ramesses IV at the Hathor temple of Serabit el-Khadim.

The sending by His Majesty build the Mansion of Millions of Years of Ramesses IV in the temple of Hathor, Lady of Turquoise, by Panefer, the Scribe of the Commands of the Army, son of Pairy, justified.

From here they could have proceeded by boat to the ports of Abu Zenima or El-Markha on the west coast of the Sinai peninsula and from there it is a short journey inland of only a day or two to the actual site of Serabit el-Khadim.

[4]Ramesses IV is attested by his aforementioned building activity at Wadi Hammamat and Serabit el-Khadim in the Sinai as well as several papyri and even one obelisk.

[4] Meanwhile, surviving monuments of Ramesses IV in the Delta consists of an obelisk recovered in Cairo and a pair of his cartouches found on a pylon gateway both originally from Heliopolis.
