"This One's for the Girls" is a song written by Chris Lindsey, Hillary Lindsey, and Aimee Mayo and recorded by American country music singer Martina McBride. It was released in June 2003 as the first single from McBride's seventh studio album, Martina. The song peaked at number three on the US Billboard Hot Country Singles & Tracks charts and at number 39 on the Billboard Hot 100. The song was also a number-one hit on the Adult Contemporary charts. A remixed version of "This One's for the Girls" was included on her 2008 compilation album Playlist: The Very Best of Martina McBride.

The song's lyrics are a salute to women of various ages (who are "about thirteen," "about twenty-five," and "about forty-two") dealing with the struggles of different phases of life–starting high school and facing new pressures, coping with uncertainty about a career, and reaching middle age–and tells them "You're beautiful the way you are." McBride's first two daughters, Delaney and Emma, sing backing vocals on the song, as do fellow country singers Carolyn Dawn Johnson and Faith Hill.
