Mons Rümker is an isolated volcanic formation that is located in the northwest part of the Moon's near side, at selenographic coordinates 40.8° N, 58.1° W. The feature forms a large, elevated mound in the northern part of the Oceanus Procellarum.{{Cite journal|last1=Zhao|first1=Jiannan|last2=Xiao|first2=Long|last3=Qiao|first3=Le|last4=Glotch|first4=Timothy D.|last5=Huang|first5=Qian|date=June 27, 2017|title=The Mons Rümker volcanic complex of the Moon: A candidate landing site for the Chang'E-5 mission|journal=Journal of Geophysical Research: Planets|language=en|volume=122|issue=7|pages=1419–1442|doi=10.1002/2016je005247|issn=2169-9097|bibcode=2017JGRE..122.1419Z |s2cid=9926094 |url=https://agupubs.onlinelibrary.wiley.com/doi/epdf/10.1002/2016JE005247|url-access=subscription}} The mound has a diameter of 70 kilometres, and climbs to a maximum elevation of about 1,300 metres above the surrounding plain. It was named after Karl L. C. Rümker.

Mons Rümker has a concentration of 22 lunar domes—rounded bulges across the top, some of which contain a small craterlet at the peak. These are wide, circular features with a gentle slope rising in elevation a few hundred meters to the midpoint. Lunar domes are similar to shield volcanoes, and are the result of lava erupting from localized vents followed by relatively slow cooling.{{Cite news|url=https://www.skyandtelescope.com/observing/a-little-guide-to-lunar-domes/|title=A Little Guide to Lunar Domes - Sky & Telescope|date=2016-09-07|work=Sky & Telescope|access-date=2018-08-16|language=en-US}}

Mons Rümker is surrounded by a scarp that separates it from the adjacent mare. The plateau rises to an altitude of 900 m in the west, 1,100 m in the south and 650 m in the east. The surface of Mons Rümker is relatively uniform, with a strong spectroscopic signature of lunar mare material. The estimated volume of lava extruded to create this feature is 1,800 km³.

A young lava plain to the northeast from Mons Rümker, named Statio Tianchuan, was the landing site of the Chang'e 5 mission.{{cite web |last=Jones |first=Andrew |url=https://www.space.com/china-chang-e-5-moon-landing-site-name |title=China's Chang'e 5 moon landing site finally has a name |work=Space.com |date=8 July 2021 |access-date=9 July 2021}}
