Kometa Čurjumov–Gerasimenko, službeno imenovana 67P/Čurjumov–Gerasimenko i ponekad skraćeno na 67P/C–G, je kometa sa trenutnim orbitalnim periodom od 6,45 godina[1] i rotacionim periodom od približno 12,4 sati.[2][3][4][5] Kao i sve druge komete, i ova je imenovana po svojim pronalazačima, Klimu Ivanoviču Čurumovu, i Svetlani Ivanovnoj Gerasimenko, koji su je prvi primijetili na fotografskoj ploči 1969.

Churyumov–Gerasimenko je cilj misije Evropske svemirske agencije Rosetta, lansirane 2. marta 2004.[6][7][8] Rosetta je imala sastanak sa Churyumov–Gerasimenko na dan 6. augusta 2014[9][10] i ušla u orbitu na dan 10. septembra 2014.[11] Rosetta-in lender, Philae, je sletio na njenu površinu 12. novembra 2014. oko 17:00h CET, postajući tako prva letjelica koja je sletjela na nukleus komete.[12][13]

Dana 30. septembra 2016., letjelica Rosetta je završila svoju misiju slijetanjem na kometin Ma'at region.[14]
