"Don't Back Down" is a song by the American rock band the Beach Boys and the final track on their 1964 album All Summer Long. Written by Brian Wilson and Mike Love, the lyrics describe a group of surfers who "don't back down from that wave", explaining that they "gotta be a little nuts" to show the girls "who's got guts". It was the group's last surfing-themed song until 1968's "Do It Again".
