Secret Treaties is the third studio album by American rock band Blue Öyster Cult, released on April 5, 1974 by Columbia.

[13] In 1975, a poll of readers of the British magazine Melody Maker voted Secret Treaties the "Top Rock Album of All Time".

The band also did not write any of the lyrics to the album, handing that duty to producer Sandy Pearlman, rock critic Richard Meltzer and singer Patti Smith.

[15] The cover, with art by Ron Lesser, depicts the band standing beside and sitting on a German ME 262 fighter aircraft; this scene is inspired by the song of the same name.

[15] Lyrics to the lead-off track "Career of Evil" were written by future punk poet Patti Smith, a longtime contributor to the band (and, at the time, girlfriend of BÖC keyboardist and rhythm guitarist Allen Lanier).

[16] The compilation Don't Fear the Reaper: The Best of Blue Öyster Cult contains a version of "Flaming Telepaths" without the music box intro.
