names = The Vela supernova remnant is a supernova remnant in the southern constellation Vela. Its source supernova exploded approximately 11,000-12,300 years ago (and was about 800 light years away). The association of the Vela supernova remnant with the Vela pulsar, made by astronomers at the University of Sydney in 1968, [cite journal |last=Large |first=M. I. |authorlink= |coauthors=Vaughan, A. E.; Mills, B. Y. |year=1968 |month= |title=A Pulsar Supernova Association? |journal=Nature |volume=220 |issue=5165 |pages=340 |doi=10.1038/220340a0 |url= |accessdate= |quote= ] was direct observational proof that supernovae form neutron stars.

The Vela supernova remnant includes NGC 2736. It also overlaps the Puppis Supernova Remnant, which is four times more distant. Both the Puppis and Vela remnants are among the largest and brightest features in the x-ray sky.
