"At Seventeen" is a song by American singer-songwriter Janis Ian from her seventh studio album Between the Lines. Columbia released it in July 1975 as the album's second single. Ian wrote the lyrics on the basis of a New York Times article and used a samba instrumental, and Brooks Arthur produced the final version. A pop and soft rock ballad, the song is about a social outcast in high school. Critics have regarded "At Seventeen" as a type of anthem. Despite her initial reluctance to perform the single live, Ian promoted it at various appearances and it has been included on compilation and live albums.
Critics praised "At Seventeen", which earned Ian the Grammy Award for Best Female Pop Vocal Performance, and Grammy nominations for Record and Song of the Year.
