"I Love You" is a song written by Keith Follesé, Adrienne Follesé and Tammy Hyler, and recorded by American country singer Martina McBride. It was released in July 1999 as the first single from her album Emotion. McBride originally recorded "I Love You" for the 1999 film's soundtrack, Runaway Bride, starring Julia Roberts and Richard Gere. The promotion the song got on the soundtrack is one of the reasons for its high chart performance. The single was then released on her upcoming album.

"I Love You" debuted at 43 on the U.S. Billboard Hot Country Singles & Tracks for the week of July 31, 1999. "I Love You" reached No. 1 on the Country Charts in late 1999 and remained there for five consecutive weeks until it was knocked off by When I Said I Do by Clint Black and Lisa Hartman Black. It is also McBride's biggest country hit to date. The song also charted at No. 24 on the Billboard Hot 100 and No. 21 on the Adult Contemporary tracks. "I Love You" is McBride's highest-charting single on the Billboard Hot 100, and was her first entry as a solo artist on the Adult Contemporary chart.

The song was later released on McBride's 2000 Greatest Hits compilation album.

The song's music video shows McBride singing in a dress at a wedding hall, with video screens of the Runaway Bride film in the background. It was directed by Gerry Wenner.
