It was a trip down memory lane as former co-stars including Hilarie Burton (Peyton), Chad Michael Murray (Lucas), Stephen Colletti (Chase), Antwon Tanner (Skills) reunited for a get-together.
Even Barry Corbin (Whitey Durham) and Lee Norris (Mouth) attended!
The reunion marked a new One Tree Hill convention held in Wilmington, North Carolina, where the show was originally filmed.
Sadly, Sophia Bush (Brooke), James Lafferty (Nathan) and Bethany Joy Lenz (Hayley) were all missing, but we're guessing it's pretty hard to get everyone together!
However, Sophia did send a message to fans via Twitter as the event took place. She said: "To everyone in NC this weekend, I wish I could split myself in two so that I could be there with all of you!! Hug my Hil for me!!"
Still, the attending cast members shared a few photos on social media and it definitely got us a little nostalgic here at Reveal HQ.
One Tree Hill was a popular American drama series set in the fictional town of Tree Hill, North Carolina, which aired from 2003 to 2012.
The series initially centred around the on and off-court rivalry between Nathan Scott and his half brother Lucas, as they both competed for positions on their school's basketball team.
In October last year, Sophia, Hilarie, Bethany and James reunited in Paris for a similar convention.
