Phillippe was born in New Castle, Delaware. His mother, Susan, ran a day care center in the family's house, and his father, Richard Phillippe, was a chemist. Phillippe is of part French descent. Phillippe graduated from the Barbizon Modeling and Acting Program in Wilmington, Delaware.
Phillippe's acting career began after being signed to Cathy Parker Management in Voorhees, New Jersey. Shortly after he made an appearance in the ABC daytime drama One Life to Live. His character Billy Douglas, whom he played from 1992 to 1993, was the first gay teenager on a daytime soap opera. After leaving the show, Phillippe moved to Los Angeles, where he appeared in a number of small parts in various television series including Matlock, Due South, the TV miniseries The Secrets of Lake Success, and movies, including the 1995 film Crimson Tide and the 1996 film White Squall.
He was cast in the 1997 horror film, I Know What You Did Last Summer, which co-starred Sarah Michelle Gellar, Freddie Prinze, Jr. and Jennifer Love Hewitt. The film was a success, and led to Phillippe gaining wider renown and being cast in a few more high-profile films, including 54 in 1998 opposite Neve Campbell, Salma Hayek and Mike Myers. In 1999 he starred in Cruel Intentions, a modern retelling of the Choderlos de Laclos novel Les Liaisons Dangereuses, which also starred Phillippe's future wife Reese Witherspoon, as well as his I Know What You Did Last Summer co-star Sarah Michelle Gellar. It was a success among its intended teenage audience, cementing Phillippe's ability to play characters that require sex appeal. Phillippe can also be seen in the Marcy Playground music video "Comin' Up From Behind", which appears on the film's soundtrack.
In the years following, he appeared in the crime drama The Way of the Gun, starred as a famed software engineer in the thriller Antitrust, and co-starred in Robert Altman's Gosford Park, which was nominated for the Oscar for Best Picture. Subsequently, Phillippe had supporting parts in the films Igby Goes Down (2002) and Crash (2005), which won the Oscar for Best Picture. His 2003 film The I Inside premiered on cable.
In 2006, Phillippe played real-life Navy corpsman John Bradley in the war film Flags of Our Fathers, directed by Clint Eastwood and following the journey of the United States Marines who lifted the flag at the Battle of Iwo Jima. Phillippe has said that the film was the "best experience" of his career because of its "personal meaning" to him, and that he would have "given [his] life" to fight in World War II, noting that both of his grandfathers fought in the war. His performance was positively received by film critic Richard Roeper, who thought it was Phillippe's best performance to date. Phillippe's next role was in the thriller Breach, in which he played FBI investigator Eric O'Neill opposite Chris Cooper. He has since commented that he believes Cooper to be "the best actor America has to offer". He then starred in Chaos, in which he plays a police officer, Five Fingers, a drama set in Morocco, Kimberly Peirce's Iraq war film Stop-Loss, and the futuristic Franklyn.
Next up for Phillippe was a rare comedic role as Lt. Dixon Piper in MacGruber, a film based on the Saturday Night Live (SNL) skit of the same name.

That same year, Phillippe starred in the Canadian/South African production The Bang-Bang Club, which tells the real-life story of the Bang-Bang Club, four South African photographers whose images documented the bloody end of apartheid. Phillippe stars as Pulitzer Prize-winning photographer Greg Marinovich. Filming for the movie took place in South Africa, beginning in March 2009. Phillippe described the filming process as "really run-and-gun. There were no comforts, and I actually appreciate that." He noted that the experience affected him, explaining that "we were shooting during the day in Soweto, and it was an endless procession of funerals—death is so common. Kids there have no quality of life. It has made me want to get more involved in Africa-based charities." An early cut of the film was shown at Cannes Film Festival in May 2009, with the final version shown at Cannes in May 2010. The film officially premiered in September 2010 at the 2010 Toronto International Film Festival.

Macy, opened on March 18, 2011, and was generally well received by critics, scoring 82% on Rotten Tomatoes as of late March 2011.

In addition to directing, co-producing, and starring in the film, Phillippe also co-wrote the script with Joe Gossett. Phillippe has said that the film is based partly on the life experiences of himself and his friends (including the filming of Straight A's in Shreveport in 2011), but is partly meant to be "a fun scary movie in the vein of Misery". Filming took place on location in Shreveport in the fall of 2012. The movie was released on October 10, 2014.
In October 2013, Phillippe began filming the thriller Reclaim in Puerto Rico.

On October 30, 2006, Phillippe and Witherspoon released a statement announcing that they were formally separating.
