Nubkheperre Intef (or Antef, Inyotef, sometimes referred to as Intef VI) was an Egyptian king of the Seventeenth Dynasty of Egypt at Thebes during the Second Intermediate Period, when Egypt was divided by rival dynasties including the Hyksos in Lower Egypt.

He is known to be the brother of Sekhemre-Wepmaat Intef—and this king's immediate successor—since he donated Louvre Coffin E3019 for this king's burial which bears an inscription that it was donated for king Sekhemre Wepmaat Intef "as that which his brother, king Antef (Nubkheperre Intef here) gives", notes Kim Ryholt. As the German scholar Thomas Schneider writes in the 2006 book Ancient Egyptian Chronology (Handbook of Oriental Studies):

Nubkheperre Intef and, by implication, his brother Sekhemre Wepmaat Intef, were probably the sons of Sekhemre Shedtawy Sobekemsaf (Sobekemsaf II today) on the basis of inscriptions found on a doorjamb discovered in the remains of a 17th Dynasty temple at Gebel-Antef on the Luxor-Farshut road. The British Egyptologist Aidan Dodson also endorses Ryholt's interpretation of the doorjamb's text and writes:

The German Egyptologist Daniel Polz, who discovered this king's tomb in 2001, also studied the same doorjamb and reached a similar conclusion in a 2007 German language book. An association between Nubkheperre Intef and a king Sobekemsaf is also indicated by the discovery of a doorframe fragment by John and Deborah Darnell in the early 1990s which preserved part of an inscription naming a king Intef ahead of a king Sobekemsaf; the hieroglyphic spelling of the king Intef here was that used only by Nubkheperre. Unfortunately, not enough of the inscription was uncovered to reveal the nature of the relationship with any certainty here—or which king Sobekemsaf was intended. Nubkheperre Intef is sometimes referred to as Intef VII, in other sources as Intef VI, and even as Intef V.

King Intef's wife was Sobekemsaf, who perhaps came from a local family based at Edfu. On an Abydos stela mentioning a building of the king are the words king's son, head of the bowmen Nakht.

Nubkheperre Intef is one of the best attested kings of the 17th dynasty who restored numerous damaged temples in Upper Egypt as well as constructing a new temple at Gebel Antef. The best preserved building from his reign is the remains of a small chapel at Koptos. Four walls that have been reconstructed show the king in front of Min and show him crowned by Horus and by another god. The reliefs are executed in raised and sunken relief. At Koptos, the Coptos Decree was found on a stela which referred to the actions of Nubkheperre Intef against Teti, son of Minhotep. At Abydos, several stone fragments were found, including columns which attest to some kind of restoration work. On a stela found at Abydos, a mention is made of a House of Intef. This most likely refers to a building belonging to Nubkheperre Intef. Therefore, while Nubkheperre Intef's highest—and only known—year date is his Year 3 on the Koptos stela, this must be considered an underestimate since he must have ruled much longer to accomplish his ambitious building program and also complete his royal tomb. Indeed, Nubkheperre Intef is alone "mentioned on over twenty contemporary monuments" from his reign which demonstrates his position as one of the most powerful rulers of the Seventeenth Dynasty of Egypt.

Numerous attestations are known, see Ryholt 1997:394 File 17/4.

Both Kim Ryholt and the German Egyptologist Daniel Polz concur that this pharaoh did not rule at or near the start of the 17th dynasty but rather late into the 17th dynasty just prior to the final three known kings of this dynasty (Senakhtenre, Seqenenre and Kamose).
