Drummer Matt Cameron on "I Am Mine":

It seems like it has all the elements this band is known for: strong lyrics, strong hook, and a good sense of melody. It wasn't a really tough decision to have that be the starting point for the record.

The lyrics for "I Am Mine" tackle existential matters. At the band's April 8, 2003 show in New Orleans, Louisiana at the UNO Lakefront Arena, Vedder stated, "This song is about what's inside you. You own it, and you have the freedom for it to come out. It's allowed to come out." At the band's July 8, 2003 show in New York City at Madison Square Garden, Vedder stated, "This song’s about personal safety, and the feeling of being secure, and even free."

"I Am Mine" was released as a single in 2002 in various versions with the previously unreleased B-sides "Down" and "Undone", both of which can also be found on the compilation album, Lost Dogs (2003), the latter as an alternate version. "I Am Mine" was the most successful song from Riot Act on the American rock charts. The song peaked at number 43 on the Billboard Hot 100, number seven on the Billboard Mainstream Rock Tracks chart, and number six on the Billboard Modern Rock Tracks chart.
