"She Knows Me Too Well" is a song written by Brian Wilson and Mike Love for the American rock band the Beach Boys, about a man who is engrossed and obsessed in his own jealousy and insecurity.

[2] It was released on the 1965 album The Beach Boys Today!, initially serving as the B-side of their "When I Grow Up (To Be a Man)" single in 1964.

"[2] According to PopMatters, The harmonically complex song perfectly expresses the tension and confusion of the lyrics, but always manages to be accessible and tuneful in a way that only Brian Wilson can pull off.

The first verse expresses his guilt, admitting “I treat her so mean, I don’t deserve what I have / And I think that she’ll forget just by making her laugh”.

He also notes that it was "a gorgeous production, but it took a little while to get used to, probably because the bittersweet chord changes and harmonies were more sophisticated than the typical pop ballad of the day.

[citation needed] The song was also released in the United Kingdom, again as the B-side of the "When I Grow Up (To Be a Man)" single, which was the band's sixth there.

"[11] American rock band Stone Temple Pilots recorded a cover version of the song during the sessions for their 1994 album Purple.
