IC 289 is a planetary nebula in the constellation Cassiopeia.[http://observing.skyhound.com/archives/oct/NGC_289.html IC 289] It was discovered by Lewis Swift in early September 1888. It lies close to the 10th magnitude star BD +60° 0631. N.J. Martin described IC 289 as "A nice, faint round planet like planetary nebula. The uniform oval disc shows some irregularity in brightness but is not obviously brighter at the edge."{{fact|date=July 2016}}

The central star of the planetary nebula is an O-type star with a spectral type of O(H).{{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}}
