The Beach Boys recorded a myriad of songs, instrumentals, and alternate versions of tracks that have never been officially released. Only recordings that have been reliably confirmed to have existed are listed here. Some of these tracks circulate on bootlegs, but many of the tapes have been lost since their creation.
This list is ordered chronologically, by recording date, and does not include non-substantial rehearsal tapes or jam sessions recorded by the group. Live recordings are included if there is no studio equivalent. Some tracks listed under certain album subheaders may not have been recorded for that particular album, but are listed as such simply to note the band's then-current album project at the time of recording.
