''' NGC 3293''' is an [[open cluster]] in the [[Carina constellation]]. It was discovered by [[Nicolas-Louis de Lacaille]] in 1751.<ref name=cseligman>{{Cite web|url=http://cseligman.com/text/atlas/ngc32a.htm#3293|title=NGC Objects: NGC 3250 - 3299|access-date=14 February 2019|website=cseligman.com|author=Seligman, Courtney}}</ref>
It consists of more than 100 stars brighter than 14th magnitude in a 10 arc minute field, the brightest of which are [[blue supergiant]]s of apparent magnitude 6.5 and 6.7.  There is also a 7th magnitude pulsating red supergiant, [[V361 Carinae]].<ref name=vltf>{{cite journal|bibcode=2006A&A...457..265D|title=The VLT-FLAMES survey of massive stars: Stellar parameters and rotational velocities in NGC 3293, NGC 4755 and NGC 6611|journal=Astronomy and Astrophysics|volume=457|issue=1|pages=265–280|last1=Dufton|first1=P.

NGC 3293 is associated with the open cluster [[NGC 3324]]. Both are fairly young, at around 12 million years old. They show some degree of [[mass segregation (astronomy)|mass segregation]], with more massive stars concentrated near their centers. Neither are [[dynamical relaxation|dynamically relaxed]].<ref name=Bisht>{{cite journal|doi=10.1093/mnras/stab691|title=Multicolour photometry and Gaia EDR3 astrometry of two couples of binary clusters (NGC 5617 and Trumpler 22) and (NGC 3293 and NGC 3324)|year=2021|last1=Bisht|first1=D.|last2=Zhu|first2=Qingfeng|last3=Yadav|first3=R K S.|last4=Ganesh|first4=Shashikiran|last5=Rangwal|first5=Geeta|last6=Durgapal|first6=Alok|last7=Sariya|first7=Devesh P.|last8=Jiang|first8=Ing-Guey|journal=Monthly Notices of the Royal Astronomical Society|volume=503|issue=4|pages=5929–5947|doi-access=free |arxiv=2103.04596}}</ref>
