This is a list of montes (mountains, singular mons) on the planet Venus. Venusian mountains are all named after goddesses in the mythologies of various cultures, except for the Maxwell Montes. The four main mountain ranges of Venus are named Akna Montes, Danu Montes, Freyja Montes, and Maxwell Montes. These are found on Ishtar Terra.
As of May 2015, 262 extraterrestrial mountains and mountain systems have official names: 117 on Venus, 50 on Mars, 48 on the Moon, 23 on Io, 13 on Titan, 9 on Iapetus, 1 on Mercury and 1 on Tethys. [3] They are named differently on different celestial bodies: [3] [13]
The origin of the Lakshmi Planum and the mountain belts such as Maxwell Montes is controversial. One theory suggests they formed over a hot plume of material rising from Venus's interior, while another says the region is being compressed (pushed together) from all sides, resulting in material descending into the planet's interior.

Venus is the second planet from the Sun, making a full orbit in about 224 days. Venus orbits the Sun at an average distance of about 0.72 AU (108 million km; 67 million mi), and completes an orbit every 224.7 days. It completes 13 orbits in 7.998 years, so its position in our sky almost repeats every eight years.
The surface of Venus is comparatively flat. When 93% of the topography was mapped by Pioneer Venus Orbiter, scientists found that the total distance from the lowest point to the highest point on the entire surface was about 13 kilometres (8.1 mi), about the same as the vertical distance between the Earth's ocean floor and the higher summits of the Himalayas.

It is sometimes called Earth's "sister planet" due to their similar size, gravity, and bulk composition (Venus is both the closest planet to Earth and the planet closest in size to Earth). The surface of Venus is covered by a dense atmosphere and presents clear evidence of former violent volcanic activity.
