Vostok Rupes is an escarpment on Mercury. The scarp is a surface manifestation of a thrust fault, which formed when the planet contracted as its interior cooled.{{cite journal|last=Watters|first=Thomas R. |author2=Solomon, Sean C. |author3=Robinson, Mark S.|title=The tectonics of Mercury: The view after MESSENGER's first flyby|journal=Earth and Planetary Science Letters|year=2009|volume=285|issue=3-4|pages=283–296|doi=10.1016/j.epsl.2009.01.025|bibcode=2009E&PSL.285..283W|display-authors=etal}}
Vostok Rupes cuts across the crater Guido d'Arezzo and across a larger, unnamed crater to the northwest.
Vostok Rupes is named after Russian ship Vostok, which led the First Russian Antarctic Expedition in 1819–1821, commanded by Fabian Gottlieb von Bellingshausen.
