Ishtar Terra /ˈɪʃtɑːr ˈtɛrə/[1] is one of the three continental regions on the planet Venus, the others being Aphrodite Terra and Lada Terra. It is a highland region named after the Akkadian goddess Ishtar, and is found in the north of the planet. In size, it is roughly between Australia and the contiguous United States, making it the second-largest of the terrae.
On its eastern edge lies the great mountain chain Maxwell Montes, which is 11 km high, compared to Mount Everest at 8.8 km. On one side of the mountain chain is an impact crater of 100 km in diameter filled with lava.[citation needed] Ishtar Terra contains the four main mountain ranges of Venus: Maxwell Montes on the eastern edge, in the north, Akna Montes on the western edge, and in the southern region. These surround the lower plain of Ishtar Terra, which is named Lakshmi Planum (after the Hindu goddess Lakshmi). Ishtar Terra also contains volcanoes named after famous women: Sacajawea, Colette, and Cleopatra. Ishtar Terra is also the site of many tesserae, formed by tectonic deformation.[citation needed]

- Note that Ishtar Terra is located near the south pole if Venus's rotation is defined as prograde by the right-hand rule.[citation needed] 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.
