List of mountains on Mars by height
# List of mountains on Mars by height

This is a list of mountains on Mars by elevation, the vertical position relative to the areoid, which is the Martian vertical datum (the surface defined as zero elevation by average martian atmospheric pressure and planet radius). Elevation is not the height above the surrounding terrain (topographic prominence).

* A mons (plural montes) is a term used in astrogeology to name extraterrestrial mountains and may or may not be of volcanic origin.
* A patera refers to the dish-shaped depression atop a volcano that is not very high compared to its diameter.
* A tholus (pl. tholi) is the term used in astrogeology to describe a small domical mountain or hill.
* Listed mons elevation is the highest point (at 16 pixels/degree) within the feature.
* Listed patera elevation is the average elevation of the shallow dish-shaped depression (the actual 'patera') at the summit.

Notable extreme elevations on Earth and Venus are included (in bold and Italics) for comparison, where the given elevations are relative to mean sea level.
