Trocmades or Trocmada was a city in the Roman province of Galatia Secunda. It appears to have been on the site of the modern Turkish village of Kaymaz, about twenty-four miles east of Eskişehir, Turkey.
The city is known from ecclesiastical records; no geographer or historian mentions a city of this name; Hierocles' Synecdemus (698, 1) gives "regio Trocnades", instead of Ρηγετνοκνάδα, referring, doubtless, to the Galatian name of some tribe on the left bank of the Sangarius.
Some writers have associated the name of Trocmades with the Galatian tribe of the Trocmi and even with the Biblical name of Togarmah, mentioned in Genesis 10:3, 1 Chronicles 1:6, and Ezekiel 27:14 and 38:6.
All the Notitiae episcopatuum up to the 13th century mention among the suffragans of Pessinus the see Τροκμάδων, meaning "of Trocmades" or "of Trocmada"; the two most recent (13th century) call it Λωτίνου; perhaps it should be Πλωτίνου, meaning "of (Saint) Plotinus", venerated there.
