Hibbard has played 63 times in the Magners League and signed a new contract at the Ospreys earlier this year, keeping him at the club for another five years.
"It's not a landmark I ever thought I'd get to but it's an achievement to be proud of," said the 26-year-old.
"Getting to 100 games for the Ospreys means a lot to me. It's my home region, it's where I'm from and where I live so I'm proud to be able to wear the shirt.
"I didn't actually think that I'd ever get to 100, at one point I believed I wouldn't even be here.
"I was playing regularly for Swansea, I probably got very close to 100 for them to be honest, and it looked as though I wasn't going to make the breakthrough here. I was probably stuck in a bit of rut to tell the truth, but the coaches here saw something in me that they like, showed a little bit of faith in me and I haven't looked back since.
"I can only put it down to working hard with Swansea and playing well there. I think that would have sent out the right message to the coaches. That's probably something that I'd advise the younger boys here now, if they are sent to play in the Premiership they've got to play well there and show the right attitude if they want to succeed at the Ospreys.
"I learnt a lot when I was at Swansea, about rugby, about myself and about my own ability and without that experience I doubt I'd have achieved what I have. I'd like to think that I've earned my stripes here now. After reaching 100 caps I suppose I become a senior player, well hopefully anyway, and I'd like to think that despite still being relatively young, I can have some input and help to make some of the younger players better."
