IC 2448 is an elliptical planetary nebula in the constellation of Carina. It was discovered in 1898 by Williamina Fleming.{{cite web|url=https://cseligman.com/text/atlas/ic24.htm#ic2448|title=New General Catalogue objects: NGC 2440 - 2449|author=Seligman, Courtney|website=cseligman.com|access-date=27 September 2019}} It lies near the bright star Beta Carinae. The central star of the planetary nebula is an O-type star with a spectral type of O(H)3 III-V.{{cite journal|doi=10.1051/0004-6361/202141916|title=Planetary nebulae in Gaia EDR3: Central star identification, properties, and binarity|year=2021|last1=González-Santamaría|first1=I.|last2=Manteiga|first2=M.|last3=Manchado|first3=A.|last4=Ulla|first4=A.|last5=Dafonte|first5=C.|last6=López Varela|first6=P.|journal=Astronomy & Astrophysics|volume=656|pages=A51|arxiv=2109.12114|bibcode=2021A&A...656A..51G|s2cid=237940344}} An analysis of Gaia data suggests that it is a binary system.{{cite journal|doi=10.1051/0004-6361/202140288|title=Towards a more complete sample of binary central stars of planetary nebulae with Gaia|year=2021|last1=Chornay|first1=N.|last2=Walton|first2=N.
