Iuput II (also spelled Yuput II) was a ruler of Leontopolis in the Egyptian Delta region of Lower Egypt who existed during the late Third Intermediate Period.

He was an ally of Tefnakht of Sais who resisted the invasion of Lower Egypt by the Kushite king Piye.

Iuput II ruled during a chaotic time of the Late Intermediate Period when several kings controlled Lower Egypt including Osorkon IV at Bubastis and prince Tefnakht at Sais.

Year 21 of Iuput II is attested on a stela from Mendes.

The respected English Egyptologist Kenneth Kitchen states that this dated stela which features Smendes, the son of Harnakht and ruler of Mendes, bears Iuput's name but lacks his royal name or prenomen.

However, the clear Lower Egyptian provenance of the stela can be associated with several monuments that name "a king Usimare Setepenamun (var.

Setepenre], Iuput Si-Bast, from the Delta" which means Iuput II's throne name was Usimare.The Year 21 stela of Iuput II was fully published in 1982.
