The Usipes (Latin: Usipi) were a Teutonlandish folk whose land lay on the right sidehill of the Rhine (and thus outside the Roman Kyserdom, in Germania), likely between the dales of the Lahn and Sieg. They are spoken of in Ptolemy's Geography and in Tacitus' Germania (chapter 32), where they are said to be one of the neighbouring folks to the Chatti and the Tencteri bewhile the 1st hundredyear AD. Dio Cassius tells an alike (if rather fewfolded) tale but puts the happenings a few years earlier. It is likely that they were the same as the Usipetes, a folk fought by Julius Caesar in 55 BC.
