"Here Today" is a song by the American rock band the Beach Boys from their 1966 album Pet Sounds. Written by Brian Wilson and Tony Asher, the lyric warns the listener of inevitable heartbreak before the narrator reveals himself to be the ex-boyfriend of the listener's newfound love. Musically, the song features an uncommon formal structure, the use of electric bass guitar as a lead instrument, and a 20-bar length instrumental break.
