YMC (the initials stand for Yiannoulas Motor Company and should not be confused with the initials unofficially used for Yamaha Motor Company) is a Greek brand of vehicles founded in early 2000s, part of Athens-based Yiannoulas Group.

Unlike earlier Greek motorcycle companies, YMC is not a proper manufacturer. It assembles a number of vehicles (scooters, motorcycles, ATVs and buggies) built mostly in China or Taiwan on (frequently) YMC designs, as production costs in Greece are now considered too high. Only specific parts for some models are actually made in Greece.
