Warburton holds the record for most caps for Wales as captain, having led the side on 35 occasions.
And the Cardiff Blues skipper, who will lead his club side in the GUINNESS PRO12 once his World Cup commitments are over, says this latest honour will be fondly cherished.
"It's an honour to receive this fellowship from a university that plays such a key role in a city and country that are a big part of my identity," said Warburton.
"I hope I can be seen as proof to other young people that if you work hard and remain committed, you can achieve your goals. It's been great to soak up the graduation atmosphere with hundreds of students who've worked hard to achieve theirs.
"It's quite surreal really, because Cardiff University is very prestigious. I attended the university for one year after finishing my A-levels, but I didn't complete the course because I went on to pursue my rugby career."
