Protean Threat is the twenty-third studio album by American garage rock band Osees, released on September 18, 2020, on Castle Face Records. Following the band's previous album, double LP Face Stabber, frontman John Dwyer has said that he intended for Protean Threat to be much like a punk album, shorter in length and composed primarily of short songs. It is the band's first full-length album to be released under the name Osees.
