Trumpler 15 is an open cluster in the constellation Carina that lies on the outskirts of the Carina Nebula.[3] Estimated ages of the stars in Trumpler 15 suggest that the cluster is slightly older than its sibling clusters Trumpler 14 and 16.[4]
It lies also above the Red Supergiant Variable star RT Carinae which is in the south of the Open cluster.
