"Be True to Your School" is a song by American rock band the Beach Boys from their 1963 album Little Deuce Coupe.

Written by Brian Wilson and Mike Love, it was issued as a single on October 28, 1963.

Hawthorne High School's fight song uses the same melody as "On, Wisconsin!".

[2] The cover photo for this single (and for the associated album Little Deuce Coupe) included member David Marks but not Al Jardine, though Jardine had returned to create a six-member band for the recording sessions for this single and album.

This single, with its B-side "In My Room", were the last two of eight charting Beach Boys songs to include Marks in the 1960s.
