Ocean Avenue is the fourth studio album by American rock band Yellowcard. It was released on July 22, 2003, through Capitol Records. After touring to promote their third album One for the Kids in 2001, the band signed to the label in early 2002. Following this, bassist Warren Cooke left the band in mid-2002, and was replaced by Inspection 12 guitarist Peter Mosely. In February and March 2003, the band recorded at Sunset Sound in Hollywood, California, with Neal Avron. Ocean Avenue is a pop-punk and punk rock album, which was compared to Blink-182 and Simple Plan.

Before Yellowcard's promotional tour of Ocean Avenue, Mosely was replaced by Alex Lewis.

The band went on a club tour of the United States, before going on tour with Less Than Jake and Fall Out Boy. "Ocean Avenue" was released as the second single on December 16, 2003.

"Only One" was released as the third and final single in June 2004; they toured Europe, Australia, and Japan. After this, they had a US tour.
