The Trocmii, also called the Trocmi, were one of three ancient tribes in Galatia, a region in central Asia Minor. These tribes included the Tolistobogii and Tectosages, and they were part of a group of Gallic people who migrated from Macedonia to Asia Minor around the early third century BCE. In 189 BCE, all three tribes were defeated by the Roman consul Gnaeus Manlius Vulso during battles at Mount Olympus and Mount Magaba.
