Gomfoi (Greek: Γόμφοι, before 1930: Ραψίστα - Rapsista;[2] Latin: Gomphi) is a village and a former municipality in the Trikala regional unit, Thessaly, Greece.

A town existed on the site of present Gomfoi in ancient times, which was renamed Philippoupolis (Greek: Φιλιππούπολις) during the reign of Philip II of Macedon.

The possession of this place was of great importance to Flamininus, since it secured him a communication with the Ambracian Gulf, from which he derived his supplies.

The capture of Gomphi was followed by the surrender of the towns named Argenta, Pherinium, Timarum, Ligynae, Strymon, and Lampsus, the position of which is quite uncertain.

[7] When Athamania revolted from Philip in 189 BCE, he marched into their country by the above-mentioned pass, but was obliged to retire with heavy loss.

[8] There can be no doubt that it was by the same route that the Roman consul Quintus Marcius Philippus marched from Ambracia into Thessaly in 169 BCE.
