The Merneptah Stele, also known as the Israel Stele or the Victory Stele of Merneptah, is an inscription by Merneptah, a pharaoh in ancient Egypt who reigned from 1213 to 1203 BCE. Discovered by Flinders Petrie at Thebes in 1896, it is now housed at the Egyptian Museum in Cairo.

The text is largely an account of Merneptah's victory over the ancient Libyans and their allies, but the last three of the 28 lines deal with a separate campaign in Canaan, then part of Egypt's imperial possessions. It is sometimes referred to as the "Israel Stele" because a majority of scholars translate a set of hieroglyphs in line 27 as "Israel". Alternative translations have been advanced but are not widely accepted.

The stele represents the earliest textual reference to Israel and the only reference from ancient Egypt. It is one of four known inscriptions from the Iron Age that date to the time of and mention ancient Israel by name, with the others being the Mesha Stele, the Tel Dan Stele, and the Kurkh Monoliths. Consequently, some consider the Merneptah Stele to be Petrie's most famous discovery, an opinion with which Petrie himself concurred.

The stele was discovered in 1896 by Flinders Petrie in the ancient Egyptian city of Thebes, and first translated by Wilhelm Spiegelberg. In his "Inscriptions" chapter of Petrie's 1897 publication "Six Temples at Thebes," Spiegelberg described the stele as "engraved on the rough back of the stele of Amenhotep III, which was removed from his temple and placed back outward, against the wall, in the forecourt of the temple of Merneptah. Owing to the rough surface, and the poor cutting, the readings in many places require careful examination... The scene at the top retains its original colouring of yellow, red, and blue. Amun is shown giving a sword to the king, who is backed by Mut on one side and by Khonsu on the other".

Now in the collection of the Egyptian Museum at Cairo, the stele is a black granite slab, over 3 meters (10 feet) high, and the inscription says it was carved in the 5th year of Merneptah of the 19th dynasty. Most of the text glorifies Merneptah's victories over enemies from Libya and their Sea People allies. The final two lines mention a campaign in Canaan, where Merneptah says he defeated and destroyed Asqaluna, Gezer, Yanoam and Israel.

Egypt was the dominant power in the region during the long reign of Merneptah's predecessor, Ramesses II, but Merneptah and one of his nearest successors, Ramesses III, faced significant invasions. The problems began in Merneptah's 5th year (1208 BCE), when a Libu king invaded Egypt from the west in alliance with various northern peoples. Merneptah achieved a great victory in the summer of that year, and the inscription is mainly about this. The final lines deal with a separate campaign in the East, where some of the Canaanite cities had revolted. Traditionally the Egyptians had concerned themselves only with cities, so the problem presented by Israel must have been something new – possibly attacks on Egypt's vassals in Canaan. Merneptah and Ramesses III fought off their enemies, but it was the beginning of the end of Egypt's control over Canaan – the last evidence of an Egyptian presence in the area is the name of Ramesses VI (1141–1133 BC) inscribed on a statue base from Megiddo.

The bulk of the inscription deals with Merneptah's victory over the Libyans, but the closing lines shift to Canaan:

The princes are prostrate, saying 'Peace!'
Not one raises his head among the Nine Bows.
Desolation is for Tjehenu;
Hatti is pacified;
Plundered is the Canaan with every evil;
Carried off is Asqaluni;
Seized upon is Gezer;
Yanoam is made non-existent;
Israel is laid waste—its seed is no more;
Kharru has become a widow because of Egypt.
All lands together are pacified.
Everyone who was restless has been bound.
