The Temple of Khonsu is an ancient Egyptian temple. It is located within the large Precinct of Amun-Re at Karnak, in Luxor, Egypt. The edifice is an example of an almost complete New Kingdom temple, and was originally constructed by Ramesses III on the site of an earlier temple. The gateway of this temple is at the end of the avenue of sphinxes that ran to the Luxor Temple. In Ptolemaic times, Ptolemy III Euergetes constructed a great gateway and enclosure wall for the temple; only the gateway now remains (see below). Inscriptions inside the forecourt of the temple were made in the time of Herihor.
The hypostyle hall was erected by Nectanebo I and is not of great size; inside were found two baboons that appear to have been carved in the time of Seti I. It probably belonged to the earlier building on the site.
Numerous blocks with unmatching and inverted decorations can be seen, showing the amount of reconstruction and reuse of material from the surrounding temple complexes, especially in Ptolemaic times.
