Raonic, who became the first Canadian to reach a Grand Slam final, made a stunning comeback after trailing two sets to one, and saved two break points in the fifth and ninth games of the fourth set before clinching the fifth set easily.
Murray, who claimed his second Wimbledon title with a 6-4, 7-6 (7/3), 7-6 (7/2) victory, looked remarkably fresh faced considering he was photographed leaving a nightclub at 3.30am the night before.
Murray did not disappoint as he claimed a third grand slam title in nearly routine fashion as he blunted Raonic's 140mph serve and made only 12 unforced errors in the final.
"From where I was kind of at the end of that year after I had the surgery, yeah, it's been quite a long, long road back". Murray came into the tournament after losing to Novak Djokovic in the finals of both the Australian Open and French Open this year.
"I would love to get to number one, for sure, and the way to do that is to show up every week and be focused on that event. I'd imagine he'll come back very strong from the loss here". "But I still feel like my best tennis is ahead of me, that I have an opportunity to win more".
That winning mentality also seems to have rubbed off on Murray as he has now contested the final of his last five tournaments, winning in Rome and Queen's Club before landing the one that really counted at the All England Club. "I had a couple of tries this year", Williams said during the trophy ceremony.
"I have, yeah, definitely had some sleepless nights, if I'm just honest, with a lot of stuff".
As well as chasing down Djokovic, Murray's says his main motivation to keep winning is to make his family proud following the birth of his daughter Sophia earlier this year. I did that and got results from it.
Rest will be the priority over the next few days with Murray having virtually confirmed he will not be playing in Great Britain's Davis Cup quarter-final against Serbia this weekend.
"It was just in the tight situations, I think I maybe dealt with them a little bit better because I've had more experience of these matches and these situations", Murray said.
During their first spell together from 2012 to 2014, the Scot won his previous two slam titles and the Olympic gold medal at the 2012 London Games.
"I don't see that being an issue this time".
Meanwhile, there was more good news for British tennis after Heather Watson won the mixed doubles final with her partner Henri Kontinen, beating Robert Farah and Anna-Lena Groenefeld 7-6, 6-4.
"I didn't just become a better tennis player after having a child".
