American Rubicon is the second full-length album from punk rock band Cobra Skulls. It was digitally released by Red Scare Industries on July 7, 2009, with a physical release following one week later on July 14. It is the band's first release with guitarist Adam Beck, who joined the band in 2008 after the departure of Charlie Parker. The title of the tenth track, "I Used to Like Them When They Put 'Cobra' in the Titles", is in reference to the band's previous album, Sitting Army, in which every track had the word "cobra" in the title.
