Trumpler 15 is an open cluster in the constellation Carina that lies on the outskirts of the Carina Nebula.{{cite web|url=http://chandra.harvard.edu/photo/2011/carina/|title=Carina Nebula: Nearby Supernova Factory Ramps U|last=Townley|first=L.|date=24 May 2011|work=Chandra X-ray Observatory|publisher=NASA|accessdate=28 April 2015}} Estimated ages of the stars in Trumpler 15 suggest that the cluster is slightly older than its sibling clusters Trumpler 14 and 16.{{citation
