Christopher John Grace was born in New York City on July 12, 1978. His mother, Pat, was the assistant to New Canaan Country School's headmaster; his father, John Grace, was a Madison Avenue executive. He has a sister named Jenny. His mother is of Irish descent, whilst his paternal grandmother came from a German-Jewish family with links to the Polish town of Kępno. Grace was raised an Episcopalian.

He grew up in Darien, Connecticut, where he became friends with Kate Bosworth in middle school and was babysat by Chloë Sevigny, who later appeared with him in high school plays.

Grace was cast as Eric Forman on Fox's That '70s Show, which debuted in 1998. He played the role regularly until the show's 7th season, when his character was written out and replaced with a new character named Randy Pearson (Josh Meyers). Grace made a brief guest appearance in the final episode. Reflecting on his experience working on the show in 2018, Grace described it as being "like a boot camp [...] for acting." He explained: "There's a filmic element, so you learn that. There's a live audience, so there's kind of a theater element. And when you suck, which you do — especially, like me, if you've never acted before — you get back up next week, do another show. And I think everyone on that show would tell you that over four or five years, we got good."

Grace played a prep school student who introduces his girlfriend to freebasing in director Steven Soderbergh's 2000 film Traffic, as well as having uncredited cameos as himself in Soderbergh's Ocean's Eleven and its 2004 sequel, Ocean's Twelve. "The joke is that you're supposed to play the worst version of yourself and I don't think too many people are comfortable with that. I never thought for a second that people were really going to think that's what I was like. I think that people will know that I was faking it in those movies", he told Flaunt magazine in 2007.^{[citation needed]}

He planned to cameo in Ocean's Thirteen. However, due to his role in Spider-Man 3, he had to abandon these plans. As Grace said, "I was doing reshoots on Spider-Man 3. I was bummed. I actually talked to Steven Soderbergh about that and we had a thing and then I couldn't do it." He appeared in director Mike Newell's 2003 film Mona Lisa Smile.

In 2004, Grace played the leading roles in Win a Date with Tad Hamilton! and In Good Company. That same year, he starred in P.S., which received only a limited theatrical release. Grace won the National Board of Review's 2004 award for Breakthrough Performance Actor for his work in In Good Company and P.S.
