Ishtar Terra Template:IPAc-en[1] is the second largest of the three continental terrae regions on the planet Venus, the others being Aphrodite Terra and Lada Terra.

It is a highland region named after the Akkadian goddess Ishtar,[2] and is found in the north of the planet.[3] Note that Ishtar Terra is located near the negative pole if Venus's rotation is defined as prograde by the right-hand rule.[4] The rotation of the planet is commonly characterized as retrograde in order to correlate its northern hemisphere with Earth's, in which case Ishtar Terra is near the north pole. This is the convention normally used for maps.

In size, it is roughly between Australia and the contiguous United States,[5] making it the second-largest of the terrae. On its eastern edge lies the great mountain chain Maxwell Montes, which is about Template:Convert high, compared to Mount Everest at Template:Convert. On one side of the mountain chain is the impact crater Cleopatra, Template:Convert in diameter filled with lava.Script error: No such module "Unsubst".

Ishtar Terra contains the four main mountain ranges of Venus: Maxwell Montes on the eastern edge, Freyja Montes in the north, Akna Montes on the western edge, and Danu Montes in the southern region. These surround the lower plain of Ishtar Terra, which is named Lakshmi Planum (after the Hindu goddess Lakshmi).[6]

Ishtar Terra also contains volcanoes named after famous women: Sacajawea and Colette. Ishtar Terra is also the site of many tesserae, made by tectonic deformation.[4]
